Honestly, it's always a balance between my morality and convenience/price.
I find it harder and harder to find any company at all with a clean enough record to be "worthy" of my business.
What Proton has done now goes beyond what I am willing to support, and I dislike the treatment of workers more than I dislike the increase in usage of LLM.
At the same time, backlash is usually an efficient way to force companies to change course, which is why I bothered for the first time ever to formulate an email to complain.
Will it make a difference this time? I doubt it.
But I'm hoping for a "No Mans Sky"-turnaround as I quite enjoy their product suite.
Time will tell.
