I imagine at least a Linux distribution created by Proton to compete with ChromeOS, which even has a large share in Linux distributions. The Proton ecosystem is there (a Google Docs-style office suite would be missing + the full integration of Standard Notes) and it could be an entry into the company’s hardware? What do you think?
No, please finish and polish the current products. Stop creating new ones before the current ones are functional.
A company can do multiple things at once.
only if they can spare the resources
There’s nothing to suggest they haven’t been able to spare the resources or hire more component people.
Hiring more people to work on new products is often a better route than hiring more people to work on the same product as well because there are fewer toes being stepped on.
