Because my last impression was that things hadn't changed. Why did you just downvote me, rather than actually provide a source to back up your claim? That isn't really conducive to a productive conversation. You've come at me in an inherently hostile manner, which is disrespectful.

Nonetheless, I'll do your work for you:

An extensive lead service pipe replacement effort has been underway since 2016. In early 2017, some officials asserted that the water quality had returned to acceptable levels, but in January 2019, residents and officials expressed doubt about the cleanliness of the water. There were an estimated 2,500 lead service pipes still in place as of April 2019. As of December 8, 2020, fewer than 500 service lines still needed to be inspected. As of July 16, 2021, 27,133 water service lines had been excavated and inspected, resulting in the replacement of 10,059 lead pipes. After $400 million in state and federal spending, Flint has secured a clean water source, distributed filters to all who want them, and laid modern, safe, copper pipes to nearly every home in the city. Politico declared that its water is "just as good as any city's in Michigan." However, a legacy of distrust remains, so residents often refuse to drink the tap water.

Furthermore:

As the criminal investigation progressed, more than a dozen state and local officials were indicted on a raft of charges, including obstruction of justice, lying to police, and involuntary manslaughter. While prosecutors were able to secure misdemeanor convictions against seven defendants through plea bargains, the most-serious charges were dropped in 2019.

So it is perhaps understandable that people think things were by and large brushed under the rug, and are still distrustful.

Earthworm Jim would be ashamed of you. He had far more modesty.
