This is the refreshening opportunity for us non-admins, and a learning opportunity to automate as much of it as possible.
Other benefits not mentioned include not signing your data or life away to whatever Google's lawyers or marketers have decided is best for them, contributing to FLOSS even if only as an end user, not being a victim of rug-pulls...the list goes on.
Obviously this isn't for everybody, because there's no denying it takes time. The point is that for many, this is a very easy tradeoff to make when factoring in all of the other benefits.
