"Such competition" feels a little awkward in American English, but the owl didn't like "Competition like that", which feels a bit more natural.
Competition like that is accepted and has been for the last three years.
"That kind of competition is good for the consumer" seems not to be accepted, although I don't see the difference.
I don't know why mine was rejected, then.
No, because 'competition' is an abstract noun (I think)
I would personally have written "benefits the consumer"(base)
It's a common phrase in politics. The truthfulness of the statement is another matter, however :)
How could possibly the competition not be beneficial for the consumer?
"Unfair" competition that uses artificially low prices to eliminate competitors only benefits consumers temporarily.
