In most jurisdictions there are, at times weaponized, limitations, and that's the tradeoff those jurisdiction landed on.
I don't see how this proposed limitation could produce acceptable weaponizations.
Just think for a second how outlandish these would sound with such limitation in place:
- The ban on "persuasive content" is used to shut down political dissent labeled as "unwanted influence."
- Independent journalists are silenced when their reporting is categorized as "promotional advertising."
- Fundraising for humanitarian causes is outlawed as "solicitation advertising."
- Religious discussions are prohibited as "advertising spiritual beliefs" or "donation to the organized religion."
- Medical awareness campaigns are shut down as "advertising health concerns."
- Environmental activism is criminalized as "advertising eco-agendas."
There would be just no end of these.
