Which is probably one reason why Slack is looking to sell to Salesforce.
My point being I don't think Slack's positioning was "chat but prettier". The fact Teams is more dominant now seems more to do with bundling.
Teams dominates because Microsoft gave it away for free to those who were already paying Microsoft.
But, you know what? Nobody cares about my opinion! You are exactly right: the people who make these decisions about what software the university "runs on" are at a far higher level, and have far more clout. Their incentives are totally misaligned with mine -- I use linux as a daily driver, and write highly mathematical software. I am exactly _not_ the target audience of these things, because, frankly, I can support myself: if something's broken, I fix it -- and don't consume IT's time. The people who _do_ however, are all of the admin staff, many of whom have professional backgrounds elsewhere, and think this is the way the world works. And they get promoted, and end up in managerial roles that make purchasing decisions at a high level. Hence, Teams.
But hey, nobody was ever fired for using Microsoft.
Sure but until the UI is so bad that you end up accidentally sending out money you didn't intend to, it is important.
Separately, In the business UI I used previously with Citizens it was so easy to get locked out of your account (and I had no time for phone calls, which was the only way to unlock it after that) that so many payments were made late because I had no other choice; my schedule was already full and the payment would only be made when I could schedule time for that stupid phone call.
That led to delays and late fees of sorts, and that is money as well, all because of a bad UX.
In the case of b2b, it’s more complicated. You’re selling to office administrators, whose goal is to score the best deal for the company. Since they aren’t the primary users of the product, stuff like UX doesn’t matter as much as cost.
Best illustrated by Slack, which thought they could sell to businesses based on a beautiful UI, but their market was dominated by Microsoft Teams, which could sell better to enterprises.
