Encryption will not protect your privacy in the specific case of Dropbox.
They look into your activity, not files.
And that’s pretty much standard for any kind of commercial SaaS, just because of security concerns.
Also, they are quite transparent about the provider they are using for internal activities (Stripe, etc.). Companies in EU will typically not disclose such information. For example, Dropbox disclose the use of AWS (for hosting the infra & code, I guess), whereas Proton does not disclose any hosting company.
Because they actually run their own infrastructure? They own their own IP space, so the only thing they’d be disclosing is the ISP’s they advertise that IP space through, which you could glean via traceroute anyways.
Don’t get me wrong, these Proton blog posts are all just thinly veiled ads for their own products, but knocking them for not being transparent about their tech is disingenuous, with their track record of the opposite. Are they open source? No. Are they forthcoming on the steps they take to protect your data (including from themselves)? You betcha.
Dropbox on the other hand has been breeches multiple times, and each time they slow walk customer notifications to try and mitigate damage to their brand, to the detriment of the customers.
I was not saying “Dropbox good” or “Proton bad”, just correcting a few things about the privacy policy in itself and what it means.
Ah yes company says competitor is no good
