That’s an arrogant attitude. Not everyone wants to or has to do that at all.
Play the game the way you want to play it. The fact you swing so hard to the opposite side makes you just as bad as the elitists that only want “get good or get lost”.
If I want to play with people who play similar to me then I will. If I want to teach new players how to play by running them through lower mythic+ or normal raids then I will. I’ve done both.
However, you saying “teach or get lost” is basically the same as saying “get good or get lost”. It’s just as arrogant and selfish because you’re telling others how to play the game. It’s a shitty close-minded mentality.
You don’t need to use IO or WP. You can choose to and that’s the important part. Having the choice to filter or not is fine. Play how you want. There’s tons of people that don’t use it. Hell even those who do are pretty lenient as my score is fairly low (1.1k) and I get invited to most 10s/15s I apply for.
