Since you refer to Chrome OS... when I say Linux I’m referring to GNU/Linux — an environment that promotes user freedom.
While it would be nice to have more people use Linux, I’m grateful for and satisfied with having something that makes my life easier (with enough critical mass participating). “Year of the Linux desktop” is simply a feel-good “nice to have” bonus, as far as I’m concerned — no market share OCD. It’s already good enough (actually fantastic!) for the people that currently care.
Who cares? 95% of the market does not find adblock user-friendly, even though they all hate commercials and complain about them, and would clearly benefit from installing it. Most people just don't care about their own experience too much, or just ignorant. The point is that Linux desktop has had a breakthrough critical mass of usage and that has lead to availability of high quality options, so in terms of usability Linux is one of best desktop/laptop options of today already. It is not about getting everyone onboard, it's about critical mass.
2020 is the Year of Linux on the Desktop.
