Here's all that matters when it comes to Agile—everything else is complete crap:
"We are uncovering better ways of developing
software by doing it"
It's entirely about learning based on experience. Uncovering, not uncovered.
"Individuals and interactions over processes and tools"
Rituals, ceremonies, Sprints, SMs, POs, various meetings. NONE of that is useful. Dump it all. Talk to people. Get feedback. Pay attention.
"Working software"
Anything that's not directly putting working software into customer's hands is just waste. Stop it.
"Responding to change over following a plan"
We learn as we work, we adapt based on what we learn.
That's it. Anybody who says "Agile" is anything other than that is selling you snake oil. Any corporation that's calling anything other than the above "Agile" is either delusional or evil.
