This wouldn't be surprising. It's sad they've let it atrophy the way that they have. My understanding is that they purchased it to train their digital assistant on the voicemails (where we would correct the transcripts for free)
Though AFAIK there's no law or contract term preventing Google from starting to charge a monthly fee in the future.
And after some time — for me it was 5+ years, porting from a baby Bell land line to a postpaid T-Mobile family plan for a couple years and then to Google Voice — your number will be tarred and feathered as a "VoIP" number and rejected for identity verification by some parties until it's ported back to a paid service (again, after some time).
Even so, it's nice that Google lets me keep the number I was born with for $0/month for as long as it lasts.
Google has already killed my sister's business's Enterprise Workspace plan, because they decided to change their mind, and make "unlimited storage" not a thing. She was paying $200/month and they now wanted $1,600/month. I decided to build a NAS for her instead.
This is despite written emails from their support confirming the use case (videography) and storage needs were suitable, and a written statement that she is "permanently grandfathered" once Google stopped offering the plan to new customers.
To make matters worse, they gave her 30 days to download all data before everything would be deleted permanently. This is how Google treats "enterprise" customers.

Where things get fun is when Google Voice IS your paid service (e.g. google fiber's phone service, popular with a certain demographic that used POTS for most their life and want to continue having a similarly behaving service).
