Free the last bits of "anything Android"?
My positive thought about this is that #PostmarketOS and #MobileLinux in general will profit from any public knowledge about hardware it could run on.
If I understood correctly the money for doing the work on the #Android blobs is donated by John Gilmore. His Money, his decision where to put it. And there is a positive effect, but there is also a negative one:
Android is based on ideas by #Google. To free it we'd need to fork it and adopt it to different ideals and goals. Android is designed to maximize the profit of Google.
It is not designed with the users well-being and interests as the primary goal.
Just replacing blobs in Android keeps the ecosystem the same, promotes Google and their goals and leaves the control over design decisions for Android in Googles hands.
Once a device is freed by hard work of a few engineers it will be old, it will be uninteresting for people looking at Android and the latest shiny hardware running it.
But still - Mobile Linux will make good use of those devices as free OSes in general do when it comes to hardware left behind by commercial OSes.
