That may mean that RDS could provide Timescale as an available extension without promoting it directly. However, that is a sufficiently gray legal area that I doubt Amazon wants to wade into it (instead of just making a competing product). The only way I think one could safely thread the needle here would be for RDS to allow you to bring your own extensions, as then Amazon is definitely not hosting it for you. However, that would compromise the security model and responsibility division that RDS provides.
