The only folks who work on matrix/riot who comment on HN are basically me (project lead) and sometimes jkire (synapse maintainer). And we don't plug the project, but respond to stuff like this & questions when they come up.

Anyone else commenting about Matrix are doing so completely independently and without any input or knowledge from the actual dev team. For instance, I have absolutely no idea who sanqui is (although I share their concern that Riot Games moving into the messaging space is awkward).

We are categorically not spamming or sockpuppeting HN: I'm afraid that folks who bring Matrix up must be doing so because they're interested or enthusiastic about the project and consider it relevant (which unfortunately it is on this thread, albeit for the wrong reasons :|)
