If someone is assembling the data they're providing a service. You think they should either NOT DO SO or NOT CHARGE FOR DOING A SERVICE?
Is there not public filings with the SEC that we can all look at... I will just go there. (guess I answered my own question). Where do these service people get their information? Why not go direct to the source?
If sifting through SEC filings is a core competency, go for it! secinfo.com or edgar provide the raw information you speak of.
