“Supporting competition” is not a good enough reason to use a shitty service. If I start a service that charges twice as much as Steam and has none of the features would you use it in order to “support competition”?
If the only reason to purchase from Epic is “they exist” that’s not good enough.
I will happily avoid Epic’s attempts to be a monopoly now over worrying that Steam might be shitty in the future.
If everything is political then it’s impossible to make a game that isn’t political. This is no more valid than someone complaining that including an option for skin tone is political.
Just pick your pronouns when you create your character. These are people getting their panties in a twist because they are being reminded that other people can choose different pronouns.
