Sure, but it doesn't change the argument. Adobe is doing really well if you look at the revenue.

Apple is the same, except in their case its the status symbol of having Apple products.

No-one gives a shit if some subset of internet warriors thinks that you will have a downfall in 10 years because of some obscure esoteric corner cases that don't affect your mainline business. Even if they are right you will probably not be around the business at that time and will have made bank.
