For you maybe, but people are vain enough to pay 20 bucks and more for a little blue check. There were insider rings charging much more for it. Time will tell though, if the easiness with which a blue checkmark is acquired will diminish the significance of having one, and to what degree.
We'll have to see. When it was "exclusive" and indicated some degree of notability, yeah, people who couldn't get it wanted it. Now it signifies you're willing to pay $250/year for a virtual hood ornament. A nice signal for scammers, but otherwise like listing yourself in "Who's Who".
I believe that it would be possible (even if not likely) for Twitter to shift into a lean state where they focus on just keeping the boat running and fostering loyalty with those who can and want to afford a subscription that's more a supporter badge than a gateway to extended features. Certainly depends on how much of their current cost is essentially ad sales and how much of that they can (and want to) cut. At least they are certainly much closer to that than anything Meta ever created or bought (with the exception of Oculus, which might certainly have been on a path to becoming a viable hardware company had it not received the Zuck's kiss of becoming deeply untrustable)
