They also left Mastodon a bit after that "due to limited resources" despite having another 12 social networks still up https://socel.net/@konato/114073103042055720
Edit: That said, to my knowledge their service is still good and hasn't been enshittified.
So Proton is abandoning Mastodon, claiming it's "due to limited resources", the icon for it is also gone from their website, yet they seem to have resources for 12 different other socials.
