Вот размышления на тему с реддита от гонконгца (протесты у них) по поводу общих групп:
I didn't mean to remove the whole feature from telegram but only wish to have an option to choose not disclosing the "groups in common" information when a stranger in a group click on my name and try to view my information, nor was I trying to make myself invisible in a group
As you all may notice, HK is currently been through a lot and telegram is used as the most popular messaging application among the protestors. Everyone joins a lot of groups and channels to keep themselves up to date with what is happening on the street. For example, if I am an accountant and lives in Texas and studied at Texas University, I'd join a Texas Group, an Accountant Group and a TexasUAlumni Group. So if a police (we Hongkongers actually prefer calling them "popo") joins all the groups, the popo can easily get these 3 pieces of personal information of me and would be able to track me easily. This is why I raised this question in the first place.
Taking this opportunity I would also like to raise your concern/draw your attention to the increasing "suicide" cases in Hong Kong. Starting from June till today, there are more than 50 cases of mysterious "suicide" cases. Many of them were either jump to death or drown to death. Last night there was a corpse discovered on the street, one of the person's foot was separated from his body but there was no blood at all. This is extremely unnatural as blood usually would be splashed everywhere unless the person was dead before being thrown off the roof.
There was another "suicide" case which a naked corpse was found in the sea on 22/9 but when the media ask to confirm the identity of the dead, the popo never replied until last night. The body was identified to belong to a 15-year-old girl who had actively participated in the antiELAB protests over the past few months. Interestingly she is also a swimming team member. And later the police said the girl committed suicide and there is nothing suspicious on this case so they closed the file and cremated her corpse today. Who would take off all their clothes before committing suicide?
There is no proof that the police murdered them and made it looks like a suicide case but I really hope telegram could help us better protect our personal identity.
