Possibly wrong marking on a chip from Ali?

To protect their ass from getting sued for trademark infringement or NDA violation ;)

Those units would NOT be delivered to microchip, but to the local market for assembly. When they leave the semicon fab, these ICs would be un-marked, in order to protect IP issues and other legal clauses. Once in the local market, these would be screen printed or laser etched with the part number and Microchip logo. It then ends up in the assembly units when these parts are requested by some one who is assembling a board. Now in this case Microchip does not make any money as the product never comes from Microchip. ...

"protect IP issues and other legal clauses" What do you mean by this statement? It looks like IP is being stolen from Microchip and remarketed with non-genuine labelling.

For e.g. a worker cannot walk out of the fab with few microchip (or any other company logo) chips and provide it to another vendor. Unmarked chips will create no suspicion when carried and delivered. If caught, then it is very difficult to find out if those parts are smuggled out of the fab. Thus they avoid any legal issue, IP rights etc..

And also some companies will do ODM, not just OEM, so the manufacturer actually has a right to sell it elsewhere, just not under that name.
The same applies to technology transfer, such as LRC making transistors for OnSemi, selling them to OnSemi, as well as under their own name.

Yes, that is possibly the way they can sell the same ICs for cheaper than the original manufacturer or distributor.

Is LCSC considerably cheaper than Digikey. I do not think so. I was comparing some prices of common ICs and I found it to be similar.

You were comparing wrong things. If you want exact IC part number from western company it won't be cheaper for many things. But you can save a lot on passives, connectors and equivalent parts. I spread my orders between 6 suppliers to get the best price: LCSC, TME, Maritex, Mouser, Farnell, Digikey.
