Same here. I used to pay for the Plus version until I found out Tutanota has a client on F-Droid and the free tier works nicely. Another thing is that I can bulk export, which is something I can't do on Protonmail unless I pay for a plan.
The only thing I don't like about Tutanota is that everything is enclosed on their apps, so you cannot use any external clients, and I rely a lot on Thunderbird. And while I can connect Protonmail through the bridge, I still need to pay for it.
In the end, I'm slowly migrating to Mailbox. It's not free, but I like it, offers a bunch of features I use and I can connect it with external clients. Tutanota is the secondary service I use.
Much to the contrary, see it as a counter-movement to that scene. Most of the bands associated with the RABM scene are fed up with the perception that Black Metal is a genre where only shitty people prevail. You will see more anarchists composing the scene though, but the main idea is standing against racism, sexism, homophobia, etc. It is not a huge movement, but this is why it is needed to bring visibility and support to these bands, mostly because they also support causes related to fights against corporations, injustice and so on.
There is a RABM community on Reddit that definitely contains more info about this, and some of the members have even engaged into investigating more about most of the bands and even creating lists pointing to sketchy stuff. Besides that, another place I use as a reference to find this band is the Antifascist Black Metal Network on YouTube. The person in charge of it is very strict on posting bands there.
If you have any questions, please let me know.
