Generally, Linux as a term refers to the Freedesktop standards, Linux kernel, and GNU userland. ChromeOS fulfills the latter two, but it lacks the Freedesktop standards, which are an essential part of the Linux platform. Therefore, it is logical to distinguish ChromeOS from standard Linux distributions since it diverges significantly from them. This differentiation has nothing to do with the Terminal, as it isn’t necessary to use it at all on most distributions. Elementary OS and Endless OS adhere to the Freedesktop standards, they are parts of the same platform as other Linux distributions.
I am quite certain that there are proportionally more communists in post-socialist countries than in Western countries. According to the results of the “Rendszerváltás 30” public opinion survey conducted in 2020 by Policy Solutions, Závecz Research, and the Friedrich-Ebert-Stiftung, 52% of the Hungarian population believes that the relative standard of living was better during the Kádár era, while 31% think it was worse. (Page 24) Of course, this doesn’t mean that 52% of the respondents are communists, but the results significantly contradict this meme. Is there any source to support the claim that there is a higher proportion of communists in Western countries compared to post-socialist countries?
I cannot speak for other countries, but here, the Kádár-era remains popular for many people even to this day, particularly among those who lived during that time.
