then why did you link them?
anyway, the point here is that they are the ones making claims, so they have the burden of proof.
as I told you already, corporations lie to their customers all the time, so it is always better to be safe and wait for the actual proof before trusting any of them.
i don't assume they are lying, I simply don't blindly believe their advertising claims without tangible evidence.
for example your claim of "no logging" is at best partially false, since their own privacy policy clearly states that IP addresses are at least temporarily collected, always and without exceptions.
who is the owner and how the company is funded is not important here, they are selling products and advertising them through claims that need verification.
