EA collect data from many different areas, so if they did change some things then it would be because a lot of people were asking for it. That can't really be helped, but I will concede that the amount of bouncebacks, tacklebacks, and tackles from behind have increased again. I don't think they make intentional changes so that people dislike the game, I just think it's a case of so many people start asking for something so they try to appease them.
Unfortunately while people are happy with the game they won't really have too much to say, but as soon as something makes them unhappy they will start to speak about it. It's like most people won't praise you for the good things you do for them, but the minute you do something bad they have something to say. It's the exact same thing, people aren't loud when it's good because they are too busy enjoying it.
People rarely answer surveys when it's good, the most people from EA will see without being told directly are probably some clips of streamers, and people won't come on here to say that things are good. They will mainly come on here when there is something bad they have to say, or they will tag EA directly in things. That makes it easy for the negativity to be heard, leading EA to believe they have to change some things.
Hopefully, that helps you understand that the situation is a bit more nuanced than it seems. The game can still be enjoyable at times, but I really think that EA need more servers to host ultimate team. Mainly due to the fact that any time it's content time or a big promo drops, the game just becomes completely bogged down. My guess is that it is the shear amount of inputs across all modes slowing the servers down, but I'm not expert so I can only guess.
