Unfortunately, most of the token project owners want people to buy their tokens from DEX to increase the number of holders and the adoption. But when the project is handled by another project where they are generating money, and the token generation comes from that platform, that is something else. You already have a huge user base on your platform, and the community is going to utilize your tokens, so you don't have to do extra marketing.
DEX is not only option for adoption but listing on DEX is helpful for project teams by saving very expensive listing cost on CEX (Centralized Exchanges).
Listing on CEX is favorite by cryptocurrency enthusiasts because they see it as one of commitment of a project team to their own project. Like spending pocket money for listing on CEX, the project team will not easily abandon that project. With project teams, listing on CEX has disadvantages too, for example, if they don't list a token on Tier-1 Centralized Exchanges, cost spent for listing will not bring good effects. Because of low trading volume on lower Tier CEX, trading volume of their token will be low, and price impacts will be very small or no impact at all.
DEX is good, and to use DEX, people must use non custodial wallets, that will help users to secure their own funds better. The team can easily to check token distribution of most of token holders are holding tokens in their non custodial wallets, not in exchange accounts. With investors in the community, watching and analyzing token distributions is important to avoid rug pulls.
