Compared to previous Civs tech trading, you gain much less free techs. And number of GS is tightly linked with your research, since you need science wonders and science buildings with scientists sitting inside. The only free techs not related to you science output are RA and GS from city-states, but you could only research very limited amount of techs this way.
Tech trading in Civ IV was not without it's abuses but a lot of those abuses were solved by selecting the no tech brokering option and the Civ IV system had an upper limit of the highest tech currently researched, you could never get ahead in tech and then stay abusing it when you were the tech lead.
