"Deliberate purpose of hindering scientific progress" is taking it too far. But:

• The Church's primary consideration in its dealings with Galileo was the preservation of its power over the masses. Not by ensuring they knew less than it did (as you say, that was an irrelevance), but by ensuring that the pope's authority was respected.
• The Church's actions were inimical to scientific progress. Not because they were wrong at the object level - as you say, the geocentric viewpoint had a reasonable amount of evidence in its favour. But they were wrong at the meta level; free and open debate between rival theories (and not just polite, well-researched debate, but also partisan screeds) is vital to scientific progress.
