Why are those companies inciting tribalism with us?

Last night I saw a twitter poll, where Bitplaza is asking users to vote on a coin they should add to their payment app: LTC or BCH

I jumped into it, but after a night of good sleep I started to think actually and ask - why are those companies inciting tribalism with us?

If they are to expand their offering on their app with ltc, or bch, is it really that hard for Bitplaza to have both added? The functioning is so similar, I think it would be an easy deal for Bitplaza to add both.
