After pushing from the gate; weather began to move in; necessitating several runway changes from Ground. After finally commencing taxi to 30L; we went down the west taxiway; and saw approximately four to five (other carrier) aircraft lined up on the east taxiway for the same runway. We taxied into number one for our side (checklists complete) when Tower gave us a precipitation advisory for departure; and said 'Tell us what you want to do'. The FO and I both agreed that it was acceptable for departure; requested a left turn; and accepted the takeoff clearance. Takeoff was uneventful until approximately 100 KIAS; when over Tower frequency we heard 'Windshear warning for departure end 30L; approximately 15 knot gain'; due to our speed; no indicators inside the aircraft were received. Immediately following Tower's call; as we neared V1; someone came on the radio and said; 'that's why no one else is taking off'; a very inappropriate time regarding the phase of flight we were in; trying to deal with a rapidly changing situation; we didn't need snarky comments congesting the radios. I quickly verbalized to the FO upon rotation 'Let's stay configured' just in case we encountered windshear. We gained approximately 10 knots; but the ride was not too rough; and we cleaned up at approximately 1000 AGL. I reported this back to Tower before switching to Departure Control. The rest of the flight was uneventful.We should have recognized the potential for windshear; and despite nothing being reported by ATC or ATIS; should have planned on the predictive windshear profile. More importantly; when someone is on takeoff roll with windshear reported; we do not need to be jamming up the radios with ancillary; snide comments. It was distracting; unnecessary; and wholly unprofessional. I don't know if Tower said anything about it to the aircraft waiting; we were a little busy.
Air carrier Captain reported a windshear warning from the tower during takeoff and commented about distracting radio communications.
