Many double blind studies are completely broken due to side effects triggering a stronger placebo response, and this is an especially huge problem for drugs like SSRIs where a placebo gets you about 80% of the benefit of the actual drug.
Similar to the study you linked, there was a more recent study where they found that for the SSRI escitalopram (aka Lexapro), the benefits disappear when you lie and tell people that they're receiving an active placebo that mimics the side effects of an SSRI. That is, if people don't actually think they're taking an SSRI, they don't get any benefit.
