TLDR; I no longer consider google trustworthy, Tiny Tiny RSS is a suitable, self hosted, replacement for Reader.
Until this week, Google had managed to convince me their services were trustworthy – more trustworthy than self-hosting – which is quite a feat , since I don’t tend to do well with faith in any context. Killing reader after it drained the rest of the RSS aggregator market took care of that illusion. Kicking the ad blockers out of the play store (on the same day) after Android had become the dominant species, and it no longer mattered that ad blockers are required to make the mobile web experience tolerable, and
intentionally breaking Jabber federation later in the week just underscore the point.
