I think it’s a good alternative for many people but it’s more like an Open-Apple mindset. In the sens that they support and contribute to free and open source software, but they do collect data for their own use. Unlike Apple they do not serve ads yet. They have been here for years and have quite good security practices making it pretty strong.

So it’s not the end-to-end encrypted alternative that people on this sub are usually looking for but could be a great fit for some users. Also they are mainly known for web hosting and VPS then they added their collaboration suite of tools named kSuite after many years which is mainly forked from popular free software.
