There is a theme of "stubbornness" here, and I just want to say not all of us are averse to learning better ways. Some of us get our first orchid, not knowing anything about them, so we follow the directions to water with ice. We may be thinking this doesn't seem right, and so we do research and we learn. Some of our information may come from a place like the Orchid Board, and then we may join that board, where we continue to learn all aspects of the hobby and end up with more orchids (the number of "more" being limited by our growing space).
So, yes, I do think it is a marketing technique developed for the purpose of making a lot of money, but some of us actually want to do right by our orchids and do take the advice of those who are more knowledgeable
BTW, that very first phal I got survived the first couple months of ice water. The roots near the top are brown and woody but still alive and it is a happy, healthy plant, thank goodness!
