Great, you have both back and leg exercises there then, with leg raise and chest flies. I'm wondering if it also allows leg curl, so you can train the other side of the thigh also.
You might want to add in bodyweight exercises in your routine to get a full body exercise. Like plank or situps for core, which I don't see any way to train with the machine.
Looks like it doesn't have any way to train legs so you should probably get something extra for that. Legs are hard to train with just bodyweight because the muscles are too strong and don't get exhausted from just the weight of your body.
Can you pull the handles in the middle towards you in a rowing motion, or is it just for pushing? If not, you need some way to train your back also. Maybe back extension would work as a bodyweight exercise.
I only use wooden spoons, spatulas and cutting boards myself. And fire retardants are obviously damaging to health, so throwing out black plastic is a good idea. But I don't think the article gives any good reason to avoid plastic in general. "Potentially harmful plastic compounds" sounds a lot like "compounds with zero evidence of being dangerous but they sound scary". Happy to be proven wrong though.
Firefox for Android has always worked great for me. I prefer it because I can install the same privacy plugins as for desktop. And they also have Firefox Focus is also great.
