Did they search for "Riot chat" first? There's another software company named Riot that currently dominates results there despite chat being auxiliary in their products. Hopefully they can shift that in their favor.
It seems like an improvement over "Vector", which is essentially un-googleable, but seriously, this trend in giving projects single common english word names is really annoying.
That is still going to be an impossible cliff to climb, they could just be washed out of search results from topical events of actual riots. Hopefully there is a plan attached to this, but it is hard to say because Vector was no better a name to start with (also gets washed out by programming documentation and cutlery sellers).
