This article seems to directly contradict some of the claims made by anti-WHO folks here. In particular, this portion of the timeline jumped out at me, contradicting the claim that the WHO was claiming no human-to-human transmission as late as early February:

On 14 January, Maria Van Kerkhove of the WHO told in a press briefing that "it is possible that there is limited human-to-human transmission, potentially among families, but it is very clear right now that we have no sustained human-to-human transmission"
The WHO recommended countries to take precautions due to the human-to-human transmission during earlier SARS and MERS outbreaks. On the same day, the WHO's Twitter account reported that "preliminary investigations conducted by the Chinese authorities have found no clear evidence of human-to-human transmission".
On 20 January, the WHO released a tweet that it was "now very clear from the latest information that there is at least some human-to-human transmission" that has occurred, given that healthcare workers had been infected.
On 22 January, WHO issued a statement stating that the data "suggests that human-to-human transmission is taking place in Wuhan", and called for more investigation.

This certainly sounds to me like they initially said that we weren't seeing human-to-human transmission in mid-Jan, but within a week or so, the data was starting to show the opposite, and they said so.
What exactly is the controversy here?
