I just generally think that adtech is toxic in a ton of ways:

* Big vector for scams and outright malware
* Positions you and the website in an adversarial relationship
* Wastes tons of resources, both energy wise and "brain power expended to make ad metrics marginally better" wise
* Requires, at least according to big companies (who may be lying about that, of course) massive profiling and tracking operations with gigantic abuse potential
* Necessitates censorship to please advertisers (outright on e.g. tiktok, "soft" / demonetization if you as much as mention a sensitive topic on YT)
* Worsens barrier to entry, since "ad supported free as the default" is often only going to be an option if you are already huge

I think an internet where we do that less and exchange money for goods and services more, and where the free stuff is for the most part free as in wikipedia or, in fact, a fedi instance, rather than free as in facebook would be a better internet overall
