I'm curious whether this approach to career/job selection is sustainable in a downturn. You can do this kind of "I quit because..." thing if you have many opportunities and options. But when things are tight? Good luck to you, as they say.
One aspect of where I work (large old tech company) is that we value those that can adapt. You aren't judged as much by your skill set as you are by how you use your skills or work with the skills others have. Sure, there are limits and this doesn't mean you become the metaphorical frog in the slowly heating pot of water.
They didn't say they'd never work somewhere with MS tools, just that that was part of the reason for leaving. I totally get it. If your employer is telling you a major part of your job is communication and giving you bad communication tools it's like if you got hired to be a chef and were given a camping stove.
There's certainly folks who enjoy the challenge or adaptation, but it does show a certain attitude towards the work and workers if your management doesn't think you need good tools to do the job well.
I'd stick around in a bad job if I thought I couldn't get something better, but it definitely means I'm looking to leave when things recover.
