For some goods (like cars) supply issues have indeed been the major driver of price inflation.
But for many consumer goods, manufacturers have exploited the perception of inflation to increase prices or (as highlighted in the source article) to shrink package volumes while retaining the same price point. It's much less clear that supply is the driver here; bear in mind the fact that moving to smaller package sizes often imposes considerable overhead as whole production lines need to be retooled, new package containers designed and manufactured etc. It's not a passive response to market phenomena, it's a straightforward investment in the idea of giving consumers less value for their money.
While I don't disagree that government policy and economic shocks can often be inflationary without any intention on the part of the business community to drive prices up, consider too that sometimes there is such intent and organizations like the Chamber of Commerce exist largely to beg for support from the public purse in hard times and deflect criticism onto whatever scapegoats are convenient in good times.
