The author arbitrarily picked an outlier looking peak to start the graph vs consumer pricing to severely bias the graphs. May 2020 (graph 100 index) has a price index of 265, but April 2020 is 185 and Jun 2020 is 194.
The PPI time series they use is indexed to the outlier you see in 2020, although that's the incorrect chart - this should be a better one: https://fred.stlouisfed.org/series/WPU0221
The conclusion is that industry PPI is down 20% since 2020, which is ridiculously misleading.
Speaking of incorrect charts, they used "Meats, poultry, fish, and eggs", which is the time series easily available on FRED, but on this timeframe is mostly about eggs - the one component irrelevant to the article.
The fact that this was written by a "Sr Data Scientist" is laughable, but probably average Silicon Valley economics.

*edit April not Feb
*Edit2: Linked wrong graph, but correct graph is like the same trend. Thank you for the correction.
