Here's a nice article answering your question and explaining the confusion here. It definitely seems like people who want to believe that covid is a hoax are taking this CDC post (which is technical and directed at scientists in testing labs) out of context and misinterpreting it to back up their narrative.

From the article:

In explaining the CDC’s decision to end the use of its own PCR test at the end of 2021, Kristen Nordlund, an agency spokeswoman, in an email to us cited “the availability of commercial options for clinical diagnosis of SARS-CoV-2 infection, including multiplexed (discussed here) and high-throughput options” — referring to technologies that use an automated process to administer hundreds of tests per day.

“Although the CDC 2019 Novel Coronavirus (2019 nCoV) Real-Time RT-PCR Diagnostic Panel met an important unmet need when it was developed and deployed and has not demonstrated any performance issues, the demand for this test has declined with the emergence of other higher-throughput and multiplexed assays,” Nordlund said.

She continued: “CDC is encouraging public health laboratories (PHL) to adopt the CDC Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay to enable continued surveillance for both influenza and SARS-CoV-2, which will save both time and resources for PHL.”
