Indeed these voices will drive some sales away, but unless other options are competitive with Bambu's offer, they still sell some of the best price-performance-reliability ratio printers on the market, and that's really attractive for the average buyer.

Most commenters here will value the openness of Prusa, but most lambda users will have limited budgets that Prusa does not cover. The U1 is a great attempt at taking on BambuLab head front, with interesting features at a reasonable price point.

In the end, a lot of people (including here) are using an iPhone even though it's locked down to a higher degree. Some people like a walled garden, some don't care.
