First I started with Louis Rossmann's video. Basically, Louis left a single line comment below a 2 year old Techlore video discussing harassment of CalyxOS and random users by Daniel Micay. Because of this one comment, Micay accused Louis of being partially responsible for swatting attacks on Micay and harassment. You can see the chat in Louis' video.
Next I decided to watch the Techlore video to get a more complete understanding. After all, it could still just be Micay strongly disliking Louis for some reason. In his video Techlore then shows multiple examples of harassment by Micay targeted at CalyxOS and random users. All examples I heard him mention are backed up with chat logs in the video.
Lastly I watched a rebuttal to Techlore's video by Tom Sparks. Howerver it was obvious he had not actually watched the whole Techlore video and Sparks also mentioned that in his rebuttal. The focus of Spark's video was mainly on the chapter on targeting various companies from Techlore's video. With that focus Sparks basically dismissed Techlore's whole video and also accused Techlore of encouraging harassment of GrapheneOS without any proof at all!
Obviously there are always single individuals in any group that harass others. Here howerver, Louis and Techlore showed up with concrete proof of inacceptable behaviour and harassment while Micay only presents himself as a victim without proof of the harassment he is alleging of others.
