You don't need to raise taxes for this, literally just stop wasting money on licensees once the open source projects are ready. It's not a "let do it in 3 months" thing, this will take at least a decade.
FramaSoft has been building "Dégooglisons" since 2001
> once the open source projects are ready.
so likely a decade or more of double spending in the meanwhile.
that's 2 election terms in France for context. Good luck making the political parties agree to this.
“Once ready” they’ll save (somewhat) on licenses, what about paying for it during the years it will take to build it, while it’s not ready?
When any random company makes a Build vs. Buy decision the question is “is this a core competency?” Most companies use a package from MS or GOOG because it’s unlikely that they’ll be so good at productivity software that it’s (A) worth distracting themselves from their actual job and (B) good enough. The same caveats apply here.
