Yes, four FTE engineers taking 18 months to upgrade across two major versions indicates a massive problem, but not necessarily with Rails or Ruby. That's a cost of $1.5M give or take, just on the engineers, not including the opportunity cost in new feature development or paying other equally important tech debt.

$7 billion dollar company, $1.5M cost? $7 BILLION. Your order of magnitudes are waaaaayyyyy off.
This is the inverse of survivor bias, in that you are retroactively applying "best practice" at the wrong scale. What gets you from $0 to $7B may hurt you at $7B. Heck, may hurt you way earlier than that.
However, and YMMV on what problem you want to solve, but saving $1.5M, heck lets 10X it and call it $15M, saving $15M when worth $7B isn't the problem I'd personally be concerned with.
