In fact, technology developed faster in medieval Europe than in most other areas, and it developed the fastest during the crusades, when military technology had to evolve in response to the tactics employed by one's enemies.
The Galileo affair was a blip on the radar, albeit an important one for symbolic reasons. In the end, Galileo's views prevailed, and the church did not go an anti-technology rampage (instead, it went on an anti-witch and anti-heretic rampage).
My major point is that if we want to criticize the church, it must be on a factual basis. It would be tragic if the 'Net brought about a new dark ages in which people believe and repeat unfounded claims just because they read someone's website.
