Your comparison to Tuft and Needle is not very good. Everybody hates mattress stores for their sleazy business practices; it's a given.
There's no unanimous hatred for Slack, however, so your ads come off as pretty ignorant. We use slack at my company and have 0 problems with it. I am perfectly aware of its limitations and I am fine with them.
Also, I have to download a desktop client to use Ryver? 2004 called and wants their software back.
Tuft and Needle also doesn't call out anyone by name. Nobody would care if Ryver's ads said "Chat programs are greedy," rather than specifically naming a beloved company.
And it's made worse since Ryver just seems to be an (inferior) Slack clone.
Actually I would find a desktop client more appealing. I'm not a fan of browsers-as-poorly-functioning-userlands-on-userlands that seems to be the modern fad.
But Slack's desktop client is excellent. Furthermore, Ryver makes a big point about guest access - and a browser client would be much better for guests than a dedicated client they may only use once.
Slack also - you can use it in browser. Most people don't want to, but I've seen some people say that they do so much work there that it's nice to have a browser tab visible.
Yeah, not having a desktop client was one of the reasons we went with Hipchat over Slack. I can understand not everyone wants to use a native app, but it sure would be a nice option.
