I'm sorry you had to experience this. Did you managed having your domains unlisted by Google?
I do understand and share your concerns about Google hegemony and nefarious impact on the web. But as I understand how web browsers and especially Google Chrome works, there is little we can do about it.
If your web browser decide arbitrarily to block your from accessing some domain because of a bundled mechanism (i.e. making requests to a private Google server that list domain names freshly registered), we can't force it to behave differently. As a workaround I would recommend using Mozilla Firefox instead, which is a web browser not owned by a despicable corporation like Google LLC.
Regarding the fact that bypassing the warning doesn't work it's probably because Google Chrome is also blocking some important security features required by CryptPad to work. I'm just guessing here because I haven't been able to find any documentation about this on Google support website. Just listing a few things CryptPad require:
- Not overwriting Content Security Policies (CSP)
- Support shared workers (or web workers if those aren't supported)
If your web browser is blocking one of these basic capabilities, CryptPad won't load.
I would recommend to bring this to Google developers, opening or participating in an already open topic on their community forum. If you have sufficient knowledge to share debug information, you can also directly open a bug report for the Chromium projects.
In case I would have not properly understood your request, please accept my apologies and don't hesitate to share your ideas about how we could deal with this on CryptPad's level.
