Isn’t it better to express your opinion with a reaction? You might not like something but can still react to it. You can express yourself as much as stickers allow you, and the best part is that you should soon be able to use your own sticker packs.

I think the Orb team should offer a welcome sticker pack for everyone that includes a like sticker. From there, people could choose to buy more if they want or stick with the included like reaction just like they would in any other Lens client app.
