When you post on reddit, instagram etc. you're giving the company your valuable data. (And it often is valuable, you put your thoughts into it and all that). Consider if you take 15 minutes to create value content, you'd get paid $5 or sth if you were doing it commercially. Now all that value is donated to big tech companies. (that's the only reason why they have value at all.)
So what's the problem with that? The problem is that reddit and others can instantaneously put your years-long effort behind a paywall. I'm not joking. Look at these:
when i want to see content on reddit (for research) or instagram (for local community) they don't allow me to see the data that users have contributed. Reddit claims that it blocks VPNs for "security reasons", meanwhile i'm using VPNs in browser's incognito mode to not be tracked. Instagram wants you to sign in sothat they amass more users and can take leverage of the network effect even more.
I can understand restricting who can post to limit bot activity, but reading must always be possible. After all, it's our data. That's exactly what happens when you give your data to big companies to "communicate with other people": your data becomes a source of income for them, at our expense.
I've been slowly replacing, by hand so it doesn't trigger their detection alerts, all of my 15 years of comments on Reddit, a lot of it valuable answers to tech questions or programming problems, with a randomly prompted unrelated paragraph of ChatGPT whatever.
When one of the first exodi(?) came, a lot people replaced their comments with random words through scripts, back then it was not as detected and prevented (which Reddit promptly scrambled to prevent), and thanks to people doing that I've eventually blocked Reddit from my Kagi altogether, simply because 90% of what I found was either questions with scrambled answers, comments that are just ads from bots, or just unrelated bullshit. So, it does have an actual impact.
Have fun selling that to AI companies.
i think the reason reddit deleted both my accounts, was so that i couldnt modify or delete my contributions.
after the accounts are deleted, they probably still have copies saved somewhere. but it revokes my access to remove or tamper with my content.
