Linux got adoption due to its features, not because of politics.
Not quite so simple. You skip why Linux was created in the beginning. It was because there was no affordable Unix alternatives available to students.
All the features we take for granted in Linux today was lacking in the beginning. It was a pretty limited OS in the beginning, only supporting a very limited set of hardware.
But Linux got adoption because it was a community wanting to builds something better, which happened to happen in the open. And it gained features through open collaboration. It was not a commercial drive itself which gave Linux the adoption.
What gave adoption was the freedom it delivered. You can call freedom a feature in this context. And others have tried to stop Linux from gaining success over the years; from Microsoft calling it a cancer, to SCO suing it for copyright issues.
The reason more and more companies decided to bet on Linux, support it in various ways, the reason some companies tried to fight Linux ... they are all based in (corporate/business) politics.
What Mozilla is doing is contrary to this. And Firefox is the immediate collateral damage, which makes the whole browser scope more difficult unless a sustainable alternative surfaces. The Chrome/Chromium dominance today is therefore a considerable threat for an open, free and sustainable browser experience.
We have already been down this path before, with Internet Explorer. We don't need to repeat these mistakes. In that sense, the Chrome browser "saved us" back then. Now Chrome/Chromium has become the new threat.
