It is a common misconception that e-Sword is run by a company, it isn’t.
Rick Meyers is e-Sword. He does the programming and everything else (and has a full time job by which he supports himself and his family) the expenses involved in maintaining e-Sword’ site and so on are defrayed by user donations.
The same goes for the Bible Support site, one person runs it, maintains it and pays for it, any donations received go to defray the expenses (and they are not small) of running the site. As such he pretty much sets the tone and the rules.
As to theological the bents of the people involved:
The e-Sword site has a link to the church where Rick Meyers worships: http://www.gracechapel.net/
I don’t know for certain about Josh, but I seem to recall he once mentioned attending a church affiliated with the Calvary Chapel.
For purposes of full disclosure, I am not in any way staff here (but I do seem to pound my keyboard a lot) the church I currently attend http://www.gracecares.net/
(I serve as a Sunday School teacher and elder) is affiliated with the CBA (Conservative Baptist Association of America); but very large part of my theology was formed while attending Calvary Community Church in Phoenix http://www.calvaryphx.com/
Personally I have found the best way to counter bad theology was with good theology. I used to study cultic teachings, but found it more efficient to study the real rather than the counterfeit.
The main thing is to insure that the words being used are properly defined, as the cultists redefine Christian words like salvation, Trinity, sin and even who Jesus is to suit their theology so that they sound Christian but mean something totally different.
My motto: “Know scripture and make sure all parties are speaking the same language.”
