Right
I just checked their website

Look at their their guide to buy bitcoin.

It says visit our buy bitcoin page and then select whether you want Bitcoin Cash or Bitcoin Core.
And when you visit that page, you see Bitcoin Cash first.
They are saying we have two kinds of bitcoin.
Every newbie visit this website is likely to make such mistake.

I just searched about owner of the domain.
Till now I didn't know the owner of bitcoin.com is Roger Ver.
If that's true, what's going on in this website is not surprising.
