The argument (if you take it in the most charitable light) is that reducing barriers to paying taxes will make people less averse to paying taxes. So they fight any effort to bring sanity to the tax code or tax payment process.
So even taken charitably I think they are wrong. But I do believe it is simply just corrupt and malicious.
You'd think the threat of having your bank accounts frozen and armed law enforcement officers showing up at your door were the most significant factors in making people "less averse" to paying taxes. I doubt reducing the barriers to filing your taxes correctly makes anyone happier about having to pay taxes either.
