As they say you know "blame the game not the player" but I say it should be the opposite for most cases, "blame the player and their actions, not the game".
We all have our little grudges with these games and certain opponents in some competitive games; we say a lot of rough stuff and may seem rude, but at the end of the day, we mean no harm, it's all just trash talk. Some people just take it too seriously I guess, bit of ego or maybe even "mental" issue is present there, without a doubt.
So, blaming videogames and the industry as a whole is not going to solve it. The developers should focus on the player's safety and try to enhance their experience to make their time and money worth every penny. While the Gov try their best to promote competitive gaming and the industry, bringing in more development and "moolah" via gaming and its huge billion dollar industry.
