CandSClean and seal.
CandS ('Clean and Seal') is an ACP contingency utility for Apple's shining 'macOS': it removes Apple's array of metadata extended attributes (XAs) that cling to everything you download (or otherwise come into contact with - today it's enough to merely open a file).
You can either drop files on its window or drop a hive root directory and click 'Recurse' and then click 'Clean and Seal'.
When dropping a single file, you have to explicitly click 'Clean and Seal'.
CandS displays the files/XAs removed. The readout can be fast.
After cleaning away the XAs, CandS seals each file by masking permissions to remove write bits. This still works, as Apple will still let you modify files by (ahem) 'unlocking' them.
CandS can also seal directories, but the option should be used cautiously, if at all.
This is What You're Looking At
This is what you're looking at.
Six tags coming from several background processes that have your Mac running at a mere fraction of its potential speed - all to slap on empty datasets?
CandS is meant to be readily available at all times, primarily for drag-drop: it 'floats' on screen and finds its home in the lower right-hand corner.
You'll need it lots.
Until someone at Apple on a par with Avie takes control, it's solutions like this people will have to use. Unless of course they're Kawasaki clones.
