I’m pretty sure every company with a “free product” does this.
That would definitely be like sabotaging your own business
Anonymity is literally the only thing Blind has. This would be complete brand suicide.
Think about the consequences. This is Blind's only winning business model. If they do that most users will leave. Let say if Facebook allows you to see who viewed your profile by just paying like LinkedIn does, how many people will stay on the platform? I wouldn't check people's LinkedIn profile if they are premium members unless it's absolutely necessary. It's just douche.
How does they being premium matter?
They can see who have viewed them even the viewers set themselves as anonymous.
sounds like something The Zuck would do
Zuck would never sell data, if nothing else it's not profitable. Sell data and make millions, don't sell data and make billions.
BTW blind is sending all your data to fb, Google etc. You can opt out of this only on fb since fb is the only platform that currently offers transparency and the ability to disconnect 3rd parties from sending data.
