Can you buy BNB without Binance?

Could you please elaborate on whether it's possible to acquire BNB tokens without utilizing the Binance platform? I'm curious to know if there are alternative methods or exchanges that facilitate the purchase of BNB, or if Binance remains the sole option for obtaining these tokens. Additionally, could you discuss any potential risks or considerations that one should take into account when exploring alternative avenues for purchasing BNB? I'm interested in understanding the full scope of options and considerations related to this matter. Thank you for your assistance.
