Sony and RyanAir have been on my "never" list for a long time, and Marriot has now joined them. Apple got on it because the first time I tried to deal with them professionally they wanted contracts which no competent professional could have permitted his employer to get stuck in and wouldn't back down when this was pointed out to them (their legal department were not the problem, it appeared to be someone else in a position of power). Prior to that of course there was the famous fast-obsolescence white cases, which within two years would be an ugly yellow so that customers would have to replace their computers if they wanted them to look at all chic - and after two years replace the replacements, and so on. Then there was the legal trolling over the last few years - employing clever lawyers to persuade courts to ignore prior art on patents and on "design". For awfulness of their reputation with me, Apple and Sony share first place.
