Hi, my siblings suggested that a present for our grandparents (younger silent generation) could be a digital picture frame that all the grandchildren could remotely upload pictures to. What I want to ask is if there are any that have an open protocol or open source alternate firmware that could be flashed to them, or otherwise can be recovered and used if the tech company making them goes out of business or just decides to stop supporting them.

So far, anything stable and user friendly enough for old people rules out trying to replicate an open source project from Hackaday, github, etc. I found and everything commercial I found seems to risk being a piece of e-waste in 6 months if the company goes out of business or decides that product isn’t making enough money to keep supporting the app.
