It is a powerful tool, but a knife can be used to hurt someone as well. Doesn’t mean knifes are universally bad.
Tracking is in many cases essential to make stuff work at all and in other cases only makes things better by allowing product improvements. Instead of universally go after anyone who has a knife in their drawer, I’d prefer to only go after those who stab someone with it.
The alternative is the cookie law we have now that leads to every site popping up cookie warnings and everyone blindly clicking accept. If we would only have to click accept for third party advertising cookies for example, people might actually pay attention to the message. But now every site just says “click yes or things will break”.
I don’t think Storj Labs use of tracking in this case should require opt in.
Other than development efforts it would depend on whether this is opt in or opt out. It comes down to the tyranny of the default. If it’s opt in, you might as well give up on getting enough data to draw any conclusions from it. Opt out for this stuff would be great, but would require changes to the node software which is currently used to collect the email addresses. And to the entire pipeline from there to the email tool being used. I would personally prefer they spend their dev time elsewhere, but reasonable people can surely disagree with that.
