Proton VPN’s pricing page exposed an ab-test identifier linked to two VPN Plus prices: €2.99/month (70% off) and €3.49/month (65% off). Repeated testing produced B → A → B → A → B, with the variant matching the rendered price each time. €12 difference over 24 months.



Way back when, the observed ABAB sequence could be explained by one server using outdated data and another having the new data and visitors being round-robined to each in turn. I have investigated issues like this and this has happened. Not sure how many companies still use a setup like this, though. It’s been K8s clusters everywhere I’ve worked for many years now. This does indeed look like a proper AB test, the HTML already looks pretty clear.
Happens all the time with GitHub Actions when they update runner images. According to Microsoft, it’s “fundamentally unfixable”.
Yeah and what’s worse is Proton denying AB testing and instead claiming that it was a promo pricing
denying the undeniable, they think we are tech illiterate fools. disgusting. is that why they left their fediverse accounts with anger? that users were pointing out lies?
They didn’t. They are active in Mastodon.
