Mmm nope, pretty sure I got that right the first time.
Most of Apple's highly touted features made their debut on Android and Samsung devices first. We iOS users owe quite a lot to Google and Samsung.
Your argument is flawed in three big ways:
1) Other than the Android engineers switching the product from Blackberry-like to iPhone-like, I would say there hasn't been a major "copy-cat" in the Google/Apple competition.
We don't regularly see Apple releasing brand new Android features to iOS, or Google announcing brand new iOS features to Android.
Features like widgets have been on Android for so long, you can hardly accuse Apple of stealing Google's idea. Plus, you can hardly credit Google with inventing widgets, particularly the implementation of widgets as it currently is on iOS.
2) Even if Apple did incorporate every Android feature, every year, so what? HTC, Samsung, Sony all release Android-based phones. Amazon forked the entire OS! Android is open source.
In production and development, open source as a development model promotes a universal access via a free license to a product's design or blueprint, and universal redistribution of that design or blueprint, including subsequent improvements to it by anyone.
3) Samsung, on the other hand, do seem to blatantly copy Apple in many areas. I'm genuinely surprised if you can't see this.
After all, features that supposedly made Samsung devices superior to iPhone, like a removable battery, or SD card slot, or even waterproofing, were all removed with the S6.
Apple added Touch ID with the iPhone 5S, Samsung added a finger print scanner to the Galaxy S5. Apple added Apple Pay to the iPhone 6, and Samsung bought & implemented a payment system with the Galaxy S6, taking advantage of Apple's groundwork ensuring companies had NFC readers.
It's hard to believe those two flagship iPhone features were added to the Galaxy line through coincidence.
Also, you might accuse Apple of copying Samsung's big-screens. But Samsung have been increasing their screens for years, and years. If Apple were to copy them as quickly as Samsung copied Touch ID and Apple Pay, we would have seen an iPhone 4S/iPhone 5 with a 4.7 inch screen.
