I don't agree. I work in cloud / ssh environments all the time. My main computer is a mac and I need to copy text to and from multiple machines and the host machine. I write C++ and other languages on all the remote machines. https://micro-editor.github.io is the only viable alternative for me as its more modern and supports all the features I would expect from this distributed environment.
1. We used Screen hero for free
2. Slack then integrated it and we had to pay to use the Screen hero feature
3. Now they kill the feature we use everyday to pairprogram. The reason why we even pay for slack.
