Not anti-Buisness
The GPL is not anti-buisness. It is pro-end-user freedom. That this freedom gets in the way of buisness sometimes is a not so unfortunate side effect.
And in any case, if your really intent on being pro-buisness then you shouldn't support any OSS at all. The ability to download BSD gets in the way of Microsoft charging you for an OS after all.
I also think you are missing some serious considerations that mean even for buisness use the GPL has advantages. For instance, why would anybody ever release software under the BSD liscense? For a buisness all it is doing is lowering the entrance cost of competition, who will find it easier to get into the buisness if they don't have to write software from the ground up. And for a single developer, the GPL forces any company that builds on my work to pay me for my work by making their changes available also.
More over, even if a company never plans to modify software, there is an advantage to the GPL. By making the code available, you fight platform lock in and can see what the system actually does. Even if the vendor goes out of buisness, my companies ability to use that platform is not destroyed.
