@HistoPol @BlackAzizAnansi there is much to fear about meta.
But there is no reason to think blocking them is actually going to achieve anything to "protect" us from them, not until there are clearer understanding of what bad behaviors to expect from them, and how federating with them would enable them.
For now, all the examples of abuse from meta i seen suggested, were based on meta threatening to de-federate us, so de-federating them in the first place is just getting there right away.
