This sentence carries a lot of weight and I don't think it's terribly truthful, or at best, speculative.
Galileo wasn't in trouble with the church because "it would get people thinking". He was in trouble because he was directly opposing the power and teachings of the church. Whether people would "think" about it I don't feel is terribly relevant, let alone something you can definitively say. Do we really know that the church was worried people would "think for themselves", or just that.
This implication is that the church knew Galileo was right. It also implies that these "things you can't say" are universally good and beneficial to society. With falsehoods neatly hand-waved away by conflating them with "people in Pittsburgh are 10 feet tall". Well, people believe the earth is flat, vaccines cause 5G, that Donald Trump won the 2020 election, and a whole host of other things that are harmful to society in varying degrees.
Being shunned for your ideas isn't evidence that you are Galileo leading the world into a bright new future. More likely you are, at best, the eccentric who should be ignored and your idea is that people in Pittsburgh are 11 feet tall.
