There were I'm fairly sure 3 Google I/Os in a row where they specifically spoke of iOS when talking about new features (probably more still, I haven't followed the livestreams anymore for them or for WWDC in like 2 years I guess). WWDC they'd do it as well (some during speeches, then the "whose devices are up to date" pie charts with like ~10% on the newest Android release of the time and >70% on the newest iOS release of the time). Microsoft did it during the Windows Phone days, but I think now they're trying to extend olive branches especially to Android, but I believe they've been nice about iOS as well.

At least one?
