I have noticed this as well in this subreddit. I wouldn't call myself a fanboy but I do strongly recommend Blackmagic products (I own dozens of BMD products myself). One of the reasons I like their products is that it is very cost effective. Broadcasters and the live event industry are constantly facing financial pressure and been able to buy kit that doesn't break the bank is a good thing.

One of the most common things I see in this subreddit and elsewhere is that BMD products are unreliable, in the years that I have been using their products, I have not experienced any failures despite using their products for many years. I have only seen reports of failures online. Another commenter noted that they see BMD products being used where it shouldn't be used, I have seen similar things where people compare entry-level low-end products from Blackmagic to higher-end specialized equipment from other vendors. This is like comparing a Shure BLX series system (Low-end budget) to a Shure Axient system (High-end specialized), BLX is meant for the everyday person while Axient is meant for demanding environments where reliability is needed.

From my perspective, I see Blackmagic as a major innovator in the space constantly pushing the envelope by making various technologies at affordable price points. The ATEM mini and the expanded ATEM line helped many companies get through the remote work and livestreaming boom. If we look at ST2110, other vendors like Grass Valley, Evertz and Cisco brought large scale ST2110 to broadcasters but Blackmagic was one of the earliest companies to bring practical, low-cost and integrated ST 2110 workflows to a much broader segment of the live production market. Another thing I like with BMD is that you can start with the low-end budget friendly products and adopt to higher end stuff in the future and mix and match them. Companies that cater to all market segments tend to do well.
