It might be morally questionable though for Twitter to hijack the Amazon links of the everyman who is just posting something with no intention of making a profit from it. I don't have a problem with that if the link doesn't have any affiliate info. But it would be morally questionable for Twitter to replace existing affiliate info with their own.
