Aug 5 at 7:04 comment added HenrikRüping I believe that the join of $EG$ and $EH$ is in general not $G\times H$-equivariantly contractible, however after restricting it is $G$-equivariantly contractible and $H$-equivariantly contractible.

Oct 18, 2023 at 13:33 comment added Z. M Let me mention that a $G\times H$-action carries potentially more structures than a $G$-action and an $H$-action. At least, there is a commutativity between two actions (and in higher algebra, such as the K-theory spectrum that you want to study, commutativity is an extra structure).
