It really looks like a script kiddy ran a script that deleted a bunch of accounts based on some unknown reason.
Which may be used as an argument. But first people affected must reach Facebook and convince it that they’re a valuable asset and ignoring them will bring harm to company’s image. Which is easier in a group, as a single person may only expect being treated as a nuisance to be shrugged off.
Simple question: Should the phone company be allowed to determine whom you can talk to and even if you can use the service in a normal way? This is the fundamental problem with communications concentrated into too few companies. It is even more of a problem when there isn't a way to rectify mistakes like are being described here.
“Should” is a deceptive word, as there is too many perspectives for its interpretation. Unless some qualification is provided, that question has no direct answer.
But it doesn’t need to have one either, because that comparison is wrong. You can’t take just any company X, compare it to a particular class of companies doing Y and then claim that because some specific rules apply to companies doing Y, company X also has to be a subject to them — despite it’s
not doing Y. Facebook is not a telecommunication company. Communication between users is merely means of achieving the goal, not the goal itself.
Sadly, this reveals weird ideas people have about entities such as Facebook or Alphabet. Which is quite a success, just like Amazon convincing people that they’re an online shopping platform. Both of them are focused on selling personal data and advertisements to customers and most services offered to other people are crafted to achieve that. And people delude themselves thinking they are customers, while they are asset or, more often, liability.
In the case of Instagram: as a content consumer, you are exchanging your personal data for a service of presenting you with images and associated features; as a content creator you are working on attracting them in exchange for a place to show some images and, if you are smart, do some promotion of your person/company/organization. No strings attached, no obligations beyond that. For either side.
Nothing like what telecoms’ services are. To telecoms you are a customer and their business model is based on you paying them for the service of offering you means to communicate. Even if some try to venture into spying on users, it’s only an additional source of income.
