Techs only cost RP if you ask for them, if someone offers them to you you don't pay any RP.
About the only time the AI will over techs to you is if you have a claim they need to compleat a colony, then they'll offer one tech and £1500.
If you play a really small minor like hawaii or haiti, other tiny minors will constanly offer you trades too.
