Mozilla is unhappy because the use of browser engines other than WebKit will be restricted to the EU, forcing them to develop two different apps.
For an independent browser like Firefox, managing two browsers is not easy, so it can be forgiven that this could be seen as almost harassment.
Also, the fact that the use of browser engines other than WebKit is limited to iOS means that the use of WebKit is still forced on iPadOS, which also increases the effort for Mozilla.
Most people not caring isn’t a concern of mine. Apple being wealthy isn’t a concern of mine. What concerns me is that the products I use flourish and develop in ways that I like. I don’t use Apple, so I don’t particularly care about them - I just watch the drama from the sidelines.
You’re not bursting my bubble in any way, but you are being a little pretentious.
