Well that is the point isn’t it. Companies are not very reliable. The only thing they can be relied on to do is whatever butters their bread and that can change at any time. There is also a PR component and a fact component and they do not always agree.
Proton is really no different. I seem to remember they changed what they said on their website after outing that activist. Presumably to be a little less misleading. Again, I am impressed with Proton but not infinitely impressed.
