According to SCMP article a few weeks ago, Outlying island residents need to settle for internet speeds nearly 100 times lower than HK Island and Kowloon residents for the same amount of money.
The average internet speed in HK Island and Kowloon is 58.11mbps, with some people getting up to 103.7mbps. Outside HK Island and Kowloon the average speed is just 2.55mbps. Lantau and Lamma get as low as 0.75mbps.
This guy is an IT system admiistrator working from home. So I think this point is very relevant. I am not sure what exactly you find so stupid about this.
