If I understand it correctly, as someone who only very recently purchased LTP 6 for Mac I think I'm actually better off as a result of the announced pricing changes. LTP X on Mac is now (I'm pretty sure it wasn't, or it certainly wasn't made clear at the time the changes were first announced) free and as I purchased it in the last 60 days I should be able to get the offered refund.
I agree, however, that the subscription charges are high for what the product is, particularly in relation to other aviation products, and suspect I'm in the minority of users. That said, I'm perfectly happy to make a note of flight times, etc. and update my logbook at home if I don't have my macbook it with me so am unlikely to subscribe to the mobile products.
