I think it’s a similar situation to the weather radars and sattelite receivers that are getting broken as more and more components of 5G are rolled out: these industries didn’t think the regulators would be so monumentally stupid as to reassign frequencies like that. Normal politics gives years of heads up before dramatic changes like these take place, but it’s been a while since normal politics have been practiced.
As for unlicensed bands themselves, I believe here in Europe several of them got moved around a bit, though that was mostly small bands that were used for devices that have since (i.e. more than 10 years ago) been altered to use Bluetooth and WiFi and other such technologies, essentially freeing up the spectrum. Someone using their thirty year old room broadcast microphone or wireless handset may be technically committing a crime, but I doubt the impact will ever register on a scale large enough to set off any investigations.
My point is that devices can and should support these kinds of regulation changes. Allowing your customers to comply with the law while using your hardware is part of their corporate responsibility.
In a way LinkedIn is federated. You create a profile or post, and within minutes hundreds of shady data brokers and contact details resellers have a copy of your post available for their customers!
I don’t really see the benefit, though. LinkedIn is functionally almost the same as Facebook, and can be replicated by adding a theme to a Friendica instance with a few custom fields. The biggest difference is that LinkedIn allows recruiters to
spam and stalk youoffer you jobs, other than that it’s just Facebook where most adults have decided to only talk about work stuff.
