Another interpretation of "other gods" (Exodus 20:3): they are called "others" because they make their worshippers into others [estranged].
Other Gods Are Those That Make Their Worshippers Into Strangers
Yalkut Shimoni on Torah 286:14
דָּבָר אַחֵר אֱלֹהִים אֲחֵרִים שֶׁהֵן עוֹשִׂים אֶת עוֹבְדֵיהֶם אֲחֵרִים.
