Your message seems a bit contradictory.

In one paragraph you say the MySQL plugin is licensed under the GPL, and in another you say one can purchase a non-GPL license.

If it is possible to purchase a non-GPL license why would you make the jump that RS has done anything other than that? Surely they are cognizant of the licensing issues involved and would have investigated this thoroughly.

Or is there information you have that is not contained within your message? Perhaps, as you imply that the Rb plugin is GPL-ed by your statement that you've asked for a non-GPL-ed plugin.

 The MySQL plugin is licensed as GPL, not as LGPL (which would allow
this). I am assuming there are serious implications for RB IDE itself since it links itself with the GPL plugin, and they advertise that they include MySQL support with the product, but that is another discussion. Unless MySQL or the GPL gives them (or has given them) an exception similar to the same exception that Linus gave the Linux kernel for modules, they could have to dance in an interesting way. The general rule is if you link with a GPL
product, your product is covered under the GPL.

To sell a closed source product that uses MySQL, you must either go to a third party MySQL plugin that is totally GPL free, or you need to contact the MySQL folks and purchase a non-GPL license from them. They are free to have a dual license for the same product since they created the product. As
creator, they can license the product different ways simultaneously.

I did give RS a feedback request for a non-GPL plugin for MySQL to RB, but they said that was MySQL's issue, not theirs. I respectfully disagree
with them, but wanted to let you folks know, just in case you had not
thought about it. RB's business is RB's business, but your business is
yours.  Please don't be caught unawares.

thanks,
Wade
