Easy-ups are not supposed to be used for bedtime in the first place, especially with a kiddo who doesn't wake up to potty. They are more for accidents. You should still be putting your kid in a nighttime diaper until they're actually getting up to pee in the middle of the night. Any product that's not meant for long term wear while being wet will give you problems like you experienced it's nothing to do with the quality of the product. You'd get that result with any of the pull-up-esque products.
About the lawsuit.. they filed suit when the new cruisers were introduced and all medical cases were dismissed as common diaper rash. You can look up any major kids brand and find some lawsuit out there against them. Anyone can write anything on the internet.
