As someone who leads and has led large organizations in the past, I can tell you that believe it or not, users across different companies talk to each other and tell each other about the shitty software they are forced to use
Eventually this leads to pressure to give them newer/better tools
Sometimes, these nontechnical users are dealing with problems as real power users that technical users may not see - there really might be a better way to do something and they may have already seen it at another company or something like that
It also happens that something might be working great but looks really dated and right or not, it can give new employees a bad impression
Still another thing is of course that sometimes someone is just throwing a hissy fit and wants something for no good reason but they somehow get the powers that be to listen to them
I’m dealing with this now - everyone is going out and buying AI tools because there is so much pressure to have AI tools and everyone feels like they are falling behind if they don’t go out and buy 10 task-specific AI tools
All that is to say that it could be that those users you referred to were facing problems that you may have been too far removed from the business to understand, it’s not a knock on you, it happens. It’s also possible they just wanted something new and shiny. The pressure to do that kind of stuff is real - I can’t imagine forcing people off of slack, for example
