I’m a little hesitant to post the spreadsheet, since most top-tier providers don’t want their information posted publicly. I reached out to each provider to ask them if they would be willing to have their service listed, what you see in the community are the providers who are comfortable posting publicly. A few more (about 6) will be posting soon, the rest have really poor quality (you can find these guys on the first page of google) and have been rejected from the community.
The community also allows providers to post updates, subscribers can discuss and give feedback, which in turn helps other folks. I think building a good quality repository of community contributions will pay off long term.
