thanks for that strong statement for FOSS in research. My experience is that the strongest impediment in switching to Linux is the lacking support by the centralised IT infrastructure. Ironically, because of security concerns they would not let researchers use other than the licenced OSes.
But regarding your statement that you rather not pay for software solutions if you don’t have to: did you consider donating the savings for the development of the open source software you are now using?
I believe FOSS only can work if the investment in development time pays off somehow. Responsibility lies with the power users, primarily in the corporate world and in developed countries. But this particularly is true for users in public service, such as universities. There is hardly a better investment opportunity for taxpayer money.
I would be curious to hear your thoughts on this.
