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.
Why?
The concept of "paying for something" isn't limited to "paying with fiat money/currency". One can "pay for something" by "paying with their attention/time", one can "pay for something" by "paying with PII" (personally-identifiable information), both situations of which are present in both Reddit's and Meta's "Sign up to read this".
Sure, Reddit and Instagram/Facebook are "free" insofar the user isn't required to do any kind of bank/credit card/cash/cryptocurrency payment, but the user ends up paying with all the time they spend in these platforms while seeing (thus, giving part of their attention span) advertisement, and also hand personal data.
When it comes to PII, even if the user set up a pseudonym and a generic PFP, the user is still handing, even if unbeknownst to the user themselves, their preferences, opinions, etc. Even lurkers end up handing PII whenever they stop at certain posts to read/see it (thus, signaling one's preferences) or use specific search queries (again, signaling one's preference).
The incognito mode may not prevent tracking (especially because of the IP address), but rotating VPNs may do. Notice I used the word "may", not "will do", because of the behavioral tracking I mentioned earlier, as well as other technical aspects (DNS leaking, browser fingerprinting, etc).
People who can afford being an actor/actress and performing very convincing alt-personas behind a VPN IP address could theoretically fool platforms enough for the person not to be tracked by their gait... except this dramaturgical skill is a behavioral tell (gait) itself. And the usage of a VPN-assigned IP address is another tell.
