The only real effect Universes Beyond has had on my life is that I need to ask my friends what their cards do more often now because I've never seen them before.
Look, I'm a certified UB hater. I refuse to buy them, I refuse to use them in my decks, I refuse to follow them in any meaningful way. But I'm not going to demand the same of others. If they want to use legal game pieces in their decks, then so be it. People gotta chill.
I agree that the pace of releases is the more serious problem than then UB. WotC used to print about a 1000 cards a year. Now, the new Star Trek has 1701 cards and it's squeezed with six other releases.
Another benefit of doing my best to ignore UB as much as possible is that it makes following new releases much more manageable! Strixhaven was great, looking forward to Reality Fracture. Two sets in consecutive order with nothing in-between.
