❗️Proton lied about A/B testing prices. Its VPN General Manager told Reddit users that the varying VPN Plus prices were leftovers from a sale that hadn't "universally refreshed."
Proton's own page source says otherwise: a meta tag, ab-test, sorts each visitor into variant A or B — B served from a separate /pricing-test URL.
$2.77/mo in one session. $3.23/mo in the next.
A/B testing prices is ordinary e-commerce. Amazon does it. Airlines do it hourly. Almost nobody would have cared.
But Proton sells privacy and trust, and criticises "big tech". That means you don't get to act as unfair like big tech does ;-)
