If the web is burned, something new will arise in its place (with new constraints) as long as there's a need. It's not like we only get one shot at this.
The constraints being different already make the replacement tangibly different
Maybe it will kill the veil of (perceived) anonimity which tangibly changes how people behave, or maybe the filter will be monetary and the filter will just affect the underclass shifting whatever discourse will be had
We can't act like whatever replaces the current web won't be different, because then there's no reason to change at all
