First, they reported on early election numbers in North Carolina which directly contradicted their poll numbers and showed Trump performing better than predicted.
Second, they outlined a clear and realistic path to Trump winning. While their own poll numbers did not support this fact, they ultimately included it. They also did not rule out a Trump win in any way.
It is always important to note that a 90% chance of winning is in no way a guarantee, and I do not believe Reuters ever truly ruled out Trump as a contender. They used the only early data available, polls--and when every poll is wrong, and psychics are still not a real thing, they did what they could with the data they had. At least, in my reading of the article you linked.
Regarding the polls you linked, those are not the Reuters/Ipsos polls of 15,000 participants. Those are much smaller polls (850 users) with far larger margins for error.
While I cannot speak to the censoring of the 11/6 poll mentioned in the second tweet, having Trump leading in popular vote nationally (eg: what polls generally check) was ultimately incorrect, regardless of what you believe. Polls need to be carefully read, interpreted, and corrected for -- which is why fivethirtyeight gave Trump a much higher chance to win than any other body.
I didn't write the code so I don't have first hand knowledge but I work for the guy who did. It was a data glitch.
It looked like Reuters' polling towards the 8th showed Trump taking the lead, but they deleted the data and replaced it with Nov 1 data. Plenty of people caught it and called them out - several people took videos as well so the chance of them being a coordinated effort to doctor screenshots seems low. I don't know if they ever responded to this issue, but it forever changed my opinion of Reuters. If we're to assume the worst about this then it's pretty disgusting if this is the kind of shady stuff the media is pulling. I sympathize in principle, but in reality the question is whether this breed of media deserves anything but contempt.

Also of note (posted elsewhere in the comments here, but downvoted): They posted this article on the 8th, saying there was a 90% chance of a Clinton win. Their data didn't support this claim.
