'Updates' that make games worse?

[dnk]

What's with the current trend of 'updates' that make games worse by adding ads or IAP? I know there were a few cases like that in the past as well (Stair Dismount, Across Age), but recently I find a few apps like that and it's annoying as there's no 'Ignore update' button.

C64 removes Bruce Lee and 2 other games.

What if we delete the game (to save space) and wants to play it later?

And does anyone know a trick to ignore these stupid updates?
