I'm not commenting on whether it's real or not (not the skills for) but only drawing attention to the supposed issue (security flaw) I saw that day :
https://github.com/ubports/ubuntu-touch/issues/2057 . See @dobey answer at the end which is rather reassuring.

@keneda It is the most current thread from the active Dev so I would say yes.

This is a known issue and it is shown in the demo videos and mentioned in many posts about the first broken 6 and 6T GSI release. It may be fixed in the new release but no one on here other than the developer has manged to install the latest version.
