Ask HN: Are any of the Olympic Hacks safe?

Multiple Articles on HN the last two days on how to watch the Olympics on your PC if your provider isn't being "helpful". Below are the list I've pulled. Since many of these are services or products I haven't used before, are there any of these you can vouch for - i.e. that will not use a Man in the Middle attack to take my passwords or install malware? List is below in the order that I understand "should" be preferred for security:
