"As a user, I don't want this" seems like a reasonable claim.
"Then you don't know what other people want" doesn't seem like a reasonable response.
People want a lot of things - but only use what they can access. Additionally, people will deliberately choose to use broken/painful systems if they have to, in order to accomplish a broader goal. Finally, the vast majority of systems used by users are built because they are profitable to build/operate. In many (most?) cases, they are not profitable to the user in the same way that they are to their builder/operator.
From those simple observations, it seems like quite stretch to claim that anything that has many users is something that people want, and that they enjoy using.
"As a user I don't want this therefore no one else should have it either." is a bit less reasonable, and implies that you don't know what other users want or care about what they need.
