There is an abundance of mediocre and even awful code in products that are not failing because of it.
The worst thing about poorly designed software architecture is that it tends to freeze and accumulate more and more technical debt. This is not always a competitive issue, and with enough money you can maintain pretty much any codebases.
Even with enough money, you may not be able to attract/keep talented engineers who are willing to put up with such a work environment (the codebase itself, and probably the culture that led to its state) and who want to ship well built/designed software but are slowed down by the mess.
