DOTA 2 gets negative reviews due to failure to release game Half Life 3

Last week, a former Valve worker named Mark published a synopsis of Half Life 2: Episode 3, a summary that was planned to be published before Mark's departure for the development of the famous series. The brief provides a small glimpse into what might have been the future of the series. However, this has reminded some people that they are angry at Valve for not leaving Half Life 3. In response, these people posted negative reviews on the DOTA 2 game page due to Valve neglecting the development of Half Life 3.
What is the relationship between DOTA 2 and Valve? The game was developed by Valve and became the most popular among gamers, providing a good opportunity for all Half Life 2 players to find another job or alternatively write negative reviews of DOTA 2 until Half Life 3 comes out, while Valve is not a bother.
Valve has decided that CS: GO and Dota 2 are much more important than Half Life 2 in her eyes, so Valve remains indifferent to the situation. Despite all this, the DOTA 2 still remains on positive balance reviews, considering that the game has received a large number of negative reviews.
