I'm not an expert in the area and hadn't heard about Sailfish before, so I took a look and stumbled on this article [0] of Rosteltelekom (Russian national company) acquiring majority in the company Jolla that produces Sailfish OS, which makes everything about Sailfish a bit less enticing from a security perspective.
Another article [1] from a few months back says that Rosteltelekom owns about 45% and Jolla is trying to find another EU company to buy those shares, but didn't see anything more recent.
