Suggestion: When I wanted to know more about the state of webOS, A made a 'status report' thread & people posted information that I added to the first post. In my signature, there are other similar threads. All I really do is make lists & ask for the data to put on them.
I see you already have a checklist. You could start a, 'List of donation links' thread & update it.
You could start with webOS Internals, webOS Ports, any other projects and developers - anyone who is active and has a donation link. I think we're always happy to take donations for our hosting costs at pivotCE. You'll probably find a lot of sources for info in the threads below.
Here's a recent example: DianBao, Telegram Client for webOS
It could be a really useful list.
