Well if vegan/​vegetarian outreach is particularly effective then it may do more to develope lab meat than just donating to lab meat causes themselves (because there would be more people interested in this and similar technologies). Additionally, making people vegan/​vegetarian may have a stronger effect in promoting anti speciesism in general which seems like it will be of larger overall benefit than just ending factory farming. This seems like it would happen because thoughts follow actions.
