While certainly demonstrative of an issue with our current society, I think it is important to remember that the video creator, while misguided, didn't do that much wrong. He is just trying to make something of himself, in fairly harmless way. In my opinion, not worthy of being burned at the stake.
Perhaps being told that some of his acts of not appreciated and are in fact causing people discomfort will cause him to be more thoughtful and maybe go a different path.
The women in the article is seemly experiencing something of Streisand effect and instead of being a no name in mildly viral tik-tok video is now in an international news article. Maybe she is passionate about the issue and the notoriety is a side-effect she is willing to bear, maybe she likes the attention.
I think this entire problem would go away if all participants were just ignored.
One thing this article does demonstrate is just as you should be suspicious of rich pastors, convincing you to give to the lord, you should also be wary of people who are making money spreading "random acts of kindness" and an online persona is perhaps entirely different then the a real persons morals. I don't know if that is the case with the creator in the video, but I that is my current exception with all people similar to this.
Overall my takeaway from this article is: Annoying young person annoys grouchy old person, a tale as old as time.
