Context
These were tax-withholding (cashless-type) sell-to-cover transactions related to RSU vesting, which are common and do not necessarily indicate the insider's view on the company. For retail investors, purchases by insiders tend to be more informative about confidence; routine withholding sales are primarily administrative.
