NGOs are often not taxed as well, for the same reason, that they benefit society. You certainly perform a public service (although most governments would consider you a threat instead, LOL), so it would be facile to start an NGO and gain all sorts of tax benefits, of more interest if you suffer from taxation keenly.

One of the more obvious attacks the Obama administration executed was auditing non-profits maliciously, as part of the suppression of Operation Wall Street and the Tea Party, starting ~2012 IIRC. I suppose that's why the Biden administration has added ~90k IRS agents.
