DiPoto was saddled with Pujols' contract and a manager stuck in the past. I don't get your point. In fact, DiPoto had to work through the mismanagement of the Angels as the power construct went from manager to owner to GM.
Angels GM DiPoto
2012: 89-73 (0.549); RS = 767, RA = 699 (finished 3rd in AL West)
2013: 78-84 (0.481); RS = 733, RA = 737 (finished 3rd in AL West)
2014: 98-64 (0.605); RS = 773, RA = 630 (finished 1st in AL West, Playoffs)
2015: 85-77 (0.525); RS = 661, RA = 675 (finished 3rd in AL West)
Angels GM Eppler
2016: 74-88 (0.457); RS = 717, RA = 727 (finished 4th in AL West)
2017: 80-82 (0.494); RS = 710, RA = 709 (finished 2nd in AL West)
2018: 80-82 (0.494); RS = 722, RA = 722 (finished 4th in AL West)
2019: 35-36 (0.493); RS = 358, RA = 360 (currently in 4th in AL West). In 71 games, 360 runs have been allowed. There are 162 games in a full season. At this current rate, the Angels will be allowing 821 runs against themselves.
Eppler hails the accumulation of Simmons, Ohtani, and Upton. Rebuilding the farm team is easier to build if you are not negating yourself of first round selections, which owner Moreno took away from DiPoto in signing Free Agents of Pujols for 2012 and Hamilton for 2013. I have explained the nuance of such facts, but you seem to omit such nuances.
Anyhow, if you have no "dog in the fight", then why are you content with Eppler considering how he's yet to bring the team to same production as his predecessor in DiPoto, who also inherited a weak farm system.

The Angels were in the bottom of the league in 2009 and 2010. Thanks to Mike Trout and Segura, they inflated the Angels' farm ranking. Once Trout was no longer a prospect, the Angels tumbled down again. Please note what Baseball America reported that the Angels kept sacrificing premium draft picks as free-agent compensations. That's what Angels owner did again in 2012 and 2013. While DiPoto has been GM for the Mariners, he hasn't sacrificed any first rounders for a Free-Agent compensation.
Now, both Eppler and DiPoto have been GMs for the past four years at their new locations, Angels and Mariners respectively. I can't use Baseball America's 2019 organizational rankings b/c you have to pay for it. So I went with Bleacher Report's rankings after the 2019 MLB draft. The Angels are ranked 21st and the Mariners are ranked 5th. Link:

Under Eppler, the Angels' pitching staff hasn't prevented Runs Allowed to be below 700 runs once in three years, and looks like it will be a fourth consecutive year. Eppler inherited an above .500 team and only two-years removed from being a playoff team. Yet, you don't see how fans can't be upset with Eppler? I wasn't upset at Eppler until after the 2018 season and reflection. Because you don't care about nuances, then you have no position to query why people are upset at Eppler.
