That’s just not true. Every coworker I know who use Linux[1] have occasional issues with webcams, mics, Slack notifications, whatever. It’s all fixable and this kind of inconvenience can be worth it when balanced with the perceived advantages, but saying driver issues are a thing of the past is just a lie.
[1]: I’ve seen these issues on Dell (XPS 13), Thinkpads, and HP laptops
