The Thalmor in the Second Era consisted of both Altmer and Bosmer. The Thalmor in the Fourth Era appear to be a solely Altmer faction. They have Bosmer that serve them, like they have Khajiit that serve them, but they are all Altmer. The 4th Era Thalmor cleared all the non-Altmer off of the Summerset Isles and have had purges in Valenwood. In those purges they kill any Bosmer that is against them. So I'd think as a whole the Bosmers probably don't like the Thalmor, but there are probably some that do.
