Sorry, I went into a bit of knowledge mode there.
The below is based on the Squeezebox Radio I have had since 2010. Things may vary for you if you have a different model.
By default, your Squeezebox radio connects via your home internet to servers at mysqueezebox.com which stream radio content to your radio - i.e. all the stations you are able to find using the dial / search function on your radio - which I am guessing is how you use it. My understanding is the mysqueezebox.com servers draw their content in turn from the popular TuneIn radio streaming service.
Additionally, there is the “Logitech Media Server” software (or LMS for short) you can download for your home computer from the Squeezebox website - https://mysqueezebox.com/ . Once installed on your home computer, you can connect your Squeezebox to LMS provided they are on the same WiFi and use it to stream e.g. music from iTunes and other media to your Squeezebox radio. Additionally, LMS has plugins you can install - some developed by Logitech, some by enthusiasts - for doing different kinds of things. You can also stream radio channels via LMS to your Squeezebox.
One of the available plug-ins for LMS which has been developed by an enthusiast allows you to stream BBC Sounds to your Squeezebox radio. I have never used this so I’m not able to comment on how well it works.
Since the BBC plan to discontinue streaming over TuneIn in March 2023, the only way after that you would be able to listen to BBC stations on your Squeezebox radio after that will be via the aforementioned plugin on LMS.
My own personal, and highly irrational objection to listening to BBC via the LMS / plugin route is I like the idea of the Squeezebox radio as a sort of standalone internet device - and I don’t want to have to switch on my laptop when I want to listen to Radio Murkyside, and at this point for me it’s just as easy to use the BBC Sounds App on tablet or phone.
Reading the Squeezebox group on Facebook, it seems quite a few enthusiasts have abandoned streaming via mysqueezebox.com and instead connect to LMS only running on their computer. Since LMS can be installed on Linux, this means it will run a Raspberry Pi computer ( https://www.raspberrypi.com/ ) and quite a few folks use this instead of having a desktop or laptop switched on all the time. I have never tried this.
Since Logitech took over Slimdevices, the original manufacturers of Squeezebox in 2006, they announced in 2012 they would discontinue support for the Squeezebox hardware and by implication the mysqueezebox.com service - which drove many users over to LMS. Reality is the mysqueezebox.com streaming service continues to be maintained by Logitech by what I imagine is a one-man-and-half-a-dog crew. For this reason, I would not expect the manufacturer to do anything in regard to the Beeb’s announcement.

On Twitter there is the @mysqueezebox page where you can reach out to Logitech’s SB team and report outages.
On Facebook there is the Squeezebox private group which is enthusiasts exchanging tips etc.
Hope this helps.
