Seems reasonable enough to me as an option staff can take up, but don’t need to if they have other accomodation or would rather live somewhere not operated by their employer.
Based on the article it seems the cost is reasonable for the area. Having a cost on the accomodation rather than it being free probably helps stop an influx of people with suitable accommodation already cancelling lease or subletting, to come stay at that building and limiting access to those that need it more. That and no doubt people who couldn’t take it up may feel shafted that their colleagues are getting a $700 a week perk if Google made it free.
No doubt one can argue the often polarising merits of office work versus remote, but if they’re going to have people come to the office having accomodation available, paid or not, no doubt would be helpful and something many other employers going through a similar transition may not be able to offer.
It’s definitely worth thinking about your use case and whether a second hand mini-pc of some sort is a better option. Along with the Pi itself many people are probably going to need a new case and quite possibly a power adapter too given the new power profile. An older PC where that’s taken care off, and where you probably have a 120GB SSD included, could be the better option for some people.
