>> It's like giving someone a deck of cards and telling them that these cards can only be used to play blackjack. You can't invent a card game, or change the rules, or build a house of cards, or do card magic.
Millions of people buy cards that can only be used to specifically only play, say; 'Magic: the Gathering' (MtG).
You could probably invent some sort of new game with MtG cards, or do some sort of card magic with them (no pun intended); but MtG cards are very intentionally not designed to be 'general purpose' cards or tools to design new card games with. They have a very specific audience in mind.
Magic the Gathering cards are also much more expensive than a regular deck of playing cards I can grab from my local dollar store. They have a lot less utility than said cards I can acquire for a $1.15CDN, taxes in; and they also have a bit of a stigma from people who seem to not like MtG for various reasons.
Somehow, still; it's one of the largest and most widely played card or tabletop games in the world; easily - and it's got an enthusiastic community of passionate and fascinating people.
Is Magic: the Gathering ruining card games? It is 'an offence against the entire notion of' what card games are?
Fuck no. Apple isn't some offence to the notion of computers, either.
Maybe it's not to your taste, but just because a product is designed for a specific set of purposes or utilities that don't suit your preference doesn't mean you have to jump to the dramatic conclusion that these products are 'ruining' the entire notion of what a product is. It's just a different product. Get over it, and use a different one. Take a valium and realize people like and use different things, and that's okay.
On a side note, I develop hobbyist apps for WatchOS, iOS, MacOS, the web; and SEGA Saturn, all on my Mac; and I've never had any issues actually achieving the results I wanted.
