The main culprits I've seen are cheaping out on quality, replacing traditional controls with touch screens or "AI" magic buttons, and squeezing in more monetization streams or adding gimmicky features that actively make the product worse.
Maybe things will turn around someday. There are a few rays of hope, like the touchscreen fad in cars gradually losing its luster, but it seems like we've been on the wrong path for a long time and I'm not sure it will ever correct.
