I hope it remains that way.
Some do of course throw unnecessary signup pages before allowing you to connect your wallet. I immediately close the tab if I see that. They are the minority.
It's the web, obviously there aren't firm rules. The point is that most of the builders in the space are hackers that want a free and open web void of that nonsense.
And most of the protocols/services are profitable, so the builders have no incentive to track users or sell data.
If "web2" companies start moving into the space, I'm sure they will track and sell data like they do now. The goal is to create free and open alternatives of those products so you aren't forced to endure those tactics.
But with web3 + a VPN or Private Relay, you can probably do a fairly good job staying mostly anon.
