Ive been checking to see if theres any basis to whats been said here, as far as I can tell Jerry and Redders radar did in fact come before gaydar.
gaydar looks to be a branch of VMRadar 1.2.1 reskinned and with the decryption code added. Everything code wise appears the same as the previously release VMRadar.
I'm not knocking gaydar, or its author for updating it with decryption, anything that helps folks is fine by me.
As for paying for support, its kind of moot really considering the guy who cracked the encryption this time round has stated they could easily move to RSA keys if this became a problem for BH, which would be infinitely more difficult to deal with. So really it don't matter if your paying $20 a month or $2000 a month, when that hits its fair to guess there will be no radars for anyone.
Also, from a personal view, Jerry was actually helping a bunch of us over on the UC forums the day he was launching his new site. Not once did he mention the site or the fact he was going to be offering a paid service (even though we were ripe customers).
With all that said, who you choose to support and where you spend your money is entirely your choice.
