The developers must also delete all installed copies of commercial Qt tools and Qt libraries. Qt customer can keep some developer licenses to continue the support of their End Customers. Bug fixing is OK. Adding new features is not OK.&lt;p&gt;Jeez I&amp;#x27;d hate to be the engineer who has to explain in court that my change was a bug fix and not a feature improvement.&lt;p&gt;Why do people even buy QT Commercial? LGPL is a very easy license to comply with. Are there better tools for commercial users or something?</text></comment>

And even what they sell is almost never even close to worth it.&lt;p&gt;The underlying technology is pretty good, so the Qv4 engine, the OS-abstractions (sockets, networking etc) and so on. But all the library code ontop can be &lt;i&gt;very&lt;/i&gt; hit or miss.&lt;p&gt;For example, they introduced new ways of handling touch events (DragHandler, TapHanderl, PinchHandler etc. etc.) which work GREAT! But they lack any way to stop propagation of events leading to them becoming utterly unusable if you have any custom &amp;quot;popup&amp;quot; things. There are also a lot of bugs with them which haven&amp;#x27;t gotten fixed in years even though they cannot be worked around. Paying for the product doesn&amp;#x27;t seem to even get you any further in that regard.&lt;p&gt;Using the open source Qt is the best option in my opinion, worst case you buy support sessions to adress specific problems but that&amp;#x27;s about it.</text></comment>
