In my opinion, I believe loot boxes should have both options of buying and earning them. Take Rainbow Six Seige for example. Players can earn Alpha packs through normal gameplay- although the chance of getting one starts out low the chance increases after every game. I also believe there are no duplicate items that can be granted. So you and I could theoretically obtain every item in this game just through traditional gameplay, albeit this would take a lot of playing. Alternatively, you can opt to simply buy the packs with premium currency, which are of course obtained via monetary transactions. A short cut for people who do not have as much time. Apex, being a free to play game I can see having some wiggle room. Though I do wish there were ways to obtain Apex packs through traditional gameplay, this being a free game and the loot boxes only giving different decals and costumes I do not mind as much.
