In response to a question I received via private msg, in case others are interested:

I too noticed that just yesterday a new issue of the FT in full PDF form was posted here. It baffles me a bit. The help person and email I received later are clear that PDFs are "not available anymore"; I asked explicitly whether it was dependent on it being a trial or fully paid subscription. The only other explanation I could come up with is that they make PDFs available to some countries and not others. That seems weird to me though, as their editions are regional (British, European, Asian, American,…), not country-wise. The edition posted yesterday was European and my subscription is from a Western European country.

Also, at least in my subscription, I did not see any historical editions either.

Perhaps others can make a trial and report what they see?

One last remark: I saw that the issue posted yesterday had a watermark added with a link. Presumably, that link is the "black source" of the PDF. I will not follow it as it seems like a Russian website and my setup is not that secure. If someone has a more secure setup and/or feels adventurous, maybe you can check out that site and report to the rest of us what you found there?

Thanks!
