> This is not about "unwilling to pay for quality tools", but completely changing the way they charge for the tools, which gets applied to all legacy software that ever used their tools, despite their previous (now deleted) clauses that new TOS won't apply unless you use the new version, is just ridiculous to me.

That's a risk you run when the company you're buying your tools from is beholden to shareholders. Which a vast majority of the companies we can even buy tools from are/will be.
