San Francisco , California ( CNN ) -- Facebook CEO Mark Zuckerberg favors the little guy , but that attitude can pose obstacles for popular websites that want to work with his company . Apple and Google , which are among the biggest technology businesses in the world , find themselves stonewalled at times by Zuckerberg and company . That sometimes results in less functional applications . Apple launched its music-centric social network , called Ping , as part of an iTunes update that contained a Facebook component . But Apple had to remove integration with the world 's largest social network hours after Ping launched . Last week Twitter announced an agreement with Apple 's Ping . Steve Jobs , Apple 's CEO , spurned Facebook for what he considered were `` onerous terms . '' When questioned about this in an interview onstage at the Web 2.0 Summit in San Francisco on Tuesday , Zuckerberg said with a shrug , `` It 's fine . '' Then Zuckerberg pointed out that the two work together in many ways . For example , Facebook 's app `` is on the vast majority of iPhones , '' he said at an event earlier this month at Facebook 's Palo Alto , California , headquarters . As for Facebook 's relationship with Google , the two are in the midst of a public spat about letting users import and export personal data between the social network and Gmail . Facebook , which launched an email service on Monday , does n't let users easily migrate addresses to other apps . Zuckerberg said at the conference on Tuesday that this move was meant to protect the private contact information of a user 's friends . He backtracked near the end of that fireside chat and highlighted the data export issue as a potential mistake . `` I 've made so many mistakes in running the company so far , '' he said . `` We still make mistakes all of the time . '' The trouble , he said , is figuring out which of the company 's myriad problems `` really matter . '' Zuckerberg also seemed to distance himself from Google , the undisputed leader in search , last month when Facebook announced a deal with Microsoft 's Bing . `` They 're just trying to rapidly gain [ market ] share by doing awesome stuff , '' Zuckerberg said of Microsoft at the Bing event . `` They 're really the underdog here . '' But Microsoft was n't spared from criticisms during Tuesday 's event . Microsoft , a massive computer software company and an investor in Facebook , has thousands of engineers , Zuckerberg pointed out ; Facebook has fewer , and is therefore seen by developers as a more effective and attractive employer , he said . Zuckerberg makes it known that he has a soft spot for budding entrepreneurs . When asked about `` The Social Network '' -- the film based on the founding of Facebook -- Zuckerberg boasted of fan mail from people who say his story inspired them to become entrepreneurs . His mission is to `` enable others to build '' social networking services , which can be accomplished using Facebook 's platform , he said . Small-time developers can freely make use of Facebook 's offerings , but larger companies must work directly or be locked out . Despite amassing 500 million people actively using the service , Zuckerberg still does n't consider Facebook a giant company . `` In some ways , I actually think we 're only now entering the zone where a lot of entrepreneurs will consider working with us , '' he said . But during Yahoo CEO Carol Bartz 's onstage interview earlier Tuesday , she described Facebook as Yahoo 's `` competition . '' This sentiment could create even greater disconnects between Facebook 's service and popular apps , as is the case with Gmail and Ping . Without being specific , Zuckerberg derided some large internet companies , saying they wo n't make it past a social networking revolution . `` Some are n't going to make it , '' he said on Tuesday . `` I think there 's an exciting opportunity for some entrepreneurs . '' Zuckerberg 's advice to `` incumbents , '' as he calls technology giants : `` Get on the bus . '' But that does n't mean he 's going to make it easy for them to board .
Facebook CEO Mark Zuckerberg called ` ` underdogs '' and entrepreneurs . Apple and Google have struggled to make apps that work well with Facebook . Small companies can freely build apps that work with Facebook .
