Out of extreme curosity I went on Ebay and put in "Quilt Patterns" and there are many. There are "Top Ebay Sellers" that write in their descriptions that these patterns are out of magazines, etc., etc. It's easy enough for anyone of us to go look, see & check for ourselves.
Many of these people have been selling on Ebay for years and have been selling patterns from magazines....have exceptional feedback and very satisfyied customers. I cannot imagine them selling for over 10 years and not knowing what they are doing. If it were illegal I doubt very seriously that they would be doing it all these years. The vast majority of Ebay sellers are very reputable and do not want to have any controversy whatsoever to diminish their good name. After all that is how they became "Top Sellers" in the first place. They are caring sellers who have a business and want to take care of their customers. I personally didn't find anything offensive about the way the pattern was as carefully as possibly pulled from the magazine (we all know how hard that might be) nor the way the templates were cut from the page. I imagine that was they only way to do it without sending a part of the magazine that did not pertain to the quilt pattern.
It's up to each individual to decide if they want to purchase a product or not and because one might choose to purchase singular pattern/patterns out of convenience for themselves does not make it wrong.
By the way I am NOT an Ebay seller but a person who has purchased many, many things off of Ebay and only had one bad experience many years ago.
