I mean microslop is pretty dang good

There's a gas station chain called Kum & Go but it's also referred to as Jizz and Jet or Ejaculate and Evacuate.

Swasticar

I have a queer friend that calls his GMC Yukon his Gay Man's Chariot. When we go places in it he usually initiates by saying something like "to the chariot"

Whole Foods -> Whole Paycheck

Walmart is its own insult.

When I had a Samsung TV, I hated it intensely and printed a label that said "scamsung." That TV eventually went to the recyclers with that label still covering the Samsung one.

McDonalds→McDicks→McPenis. I'm mature.

Found On Road Dead

Just Empty Every Pocket

Fix It Again Tony

The American embassy for McDonalds

There’s a trucking company called Swift that gets a lot of flak for hiring inexperienced drivers. One of the nicer ones is So What I Failed Training. The rudest one I’ve heard ends with Toddlers, you can probably work out the rest, but you probably shouldn’t.

"Home Despot" is one of my favs from Joey Santore of crime pays but botany doesn't.

Nintendon't on account of their rabid intellectual property protection and litigious nature.

Works as both what they might say to would-be infringers as well as advice to avoid them. (Which people ignore because Zelda, Mario and childhood memories.)

Always remember that Microsoft literally means small and limp.

Ford = Found On Road Dead

Dodge (n.) - To avoid

Samsung --> Samsucks

PlayStation --> PayStation (Not a company name, but relevant enough)

Edit: more names I came up with (I don't use all of these but they are reserved in case I have to):

Roblox --> Blowblox

Discord --> Disscord

Apple --> Crapple

McDonald's --> FakeDonald's

Dunkin --> Bunkin

Sam's Club --> Scam's Club

Fiat: Fix It Again Tomorrow, Lotus: Lots Of Trouble, Usually Serious

Food court near me named Choices gets called "Chances".

Pontiac stands for Poor Old Neanderthal Thinks It's A Cadillac.

Cock-a-Cola

Pisspi

Dr. Pecker

Shitzza Hut

Little Weiners

Mountain DooDoo

Ball-Mart

Worst Buy

Shams Club

Panda Sex Press

Sub-standard Way

Some friendlier ones. There was once an expensive camera brand called "Exakta" but Exakta owners affectionately called them "Approxima".

I worked near a slightly fancy Chinese restaurant called Royal East but my coworkers (who went there often) liked to call it "Royal Eats".

There was a nearby supermarket called Purity Supreme but people called it Poverty Supreme. That was waaaay before Whole Foods.

Amherst, Massachusetts was sometimes anagrammed to "Hamster". I mean you could address letters that way and they'd get there.

McDoogles and Brogger Krog for mcds and burger king. Not sure why..

Charbucks

Delta

Don’t Expect Luggage To Arrive

-or-

Doesn’t Ever Leave The Airport

Accidenture.

Idiots Become Managers

Broadcum

But I've also just seen IBM and broadcom be used a verb for price hikes or rug pulls.

I still call it reddit. It is already the name of a joke of a corporation.

In our household McDonald's is nearly universally McZargald's, based on the Calvin and Hobbes strip. They're not much good for anything except a reliable place to stop and take a leak when you're on the hyperspace bypass anyway.

Similarly, I don't think anyone in my circle has referred to that Baja Blast, chalupa, and fried chicken establishment as anything other than "Cluckin' Bell" for several decades thanks to the early 3D GTA games.

Before they became Microslop, they were Micro$haft in the IT world. The double entendre is self explanatory.

I sometimes call McDonalds „The Gilded Seagull Inn“
